Understanding the Photoexcitation of Room Temperature Ionic Liquids
Authors: Leier Julia , Michenfelder Nadine C. , Unterreiner Andreas‐Neil 
Published: December 2020

AbstractPhotoexcitation of (neat) room temperature ionic liquids (RTILs) leads to the observation of transient species that are reminiscent of the composition of the RTILs themselves. In this minireview, we summarize state‐of‐the‐art in the understanding of the underlying elementary processes. By varying the anion or cation, one aim is to generally predict radiation‐induced chemistry and physics of RTILs. One major task is to address the fate of excess electrons (and holes) after photoexcitation, which implies an overview of various formation mechanisms considering structural and dynamical aspects. Therefore, transient studies on time scales from femtoseconds to microseconds can greatly help to elucidate the most relevant steps after photoexcitation. Sometimes, radiation may eventually result in destruction of the RTILs making photostability another important issue to be discussed. Finally, characteristic heterogeneities can be associated with specific physicochemical properties. Influencing these properties by adding conventional solvents, like water, can open a wide field of application, which is briefly summarized.
Reconsidering the role of the built environment in human–wildlife interactions
Authors: Serenari Christopher 
Published: December 2020

AbstractIn facing our greatest challenges, researchers have questioned where the ‘wild things’ will reside in the future, and large carnivores have been a primary focal area.The built environment plays a critical role in the propagation of countless species including carnivores; however, contemporary conceptualizations of human–nature relations do not satisfactorily attend to where the built environment should be placed within existing human–nature relation frameworks or how it impacts our ability to find space for carnivores.This paper fills this information gap by investigating the role of the built environment in social–ecological systems (SES), specifically wildlife and carnivore conservation.The paper unfolds in four stages: The first reviews empirical efforts to capture the relationship between human–natural–wildlife systems and the built environment. Second, using insights from the built environment literature, I argue that moving away from a common pool resource focus, decoupling wildlife and natural systems, investigating all infrastructure types and their interactions across systems, and considering the notion of hybrid systems offer pathways forward. Third, an explanation of the built environment's linkages to human and carnivore systems is undertaken to illustrate how the built environment facilitates the material and symbolic interactions through a blending of properties from human, wildlife and natural systems. Lastly, the argument is made that attending to the role of the built environment in human–wildlife relations can stimulate new research that reveals unhelpful habitual behaviour, feedbacks and barriers, and may also help explain unintended or unexplained consequences impacting human–carnivore relations not fully considered under existing frameworks.A freePlain Language Summarycan be found within the Supporting Information of this article.
State anxiety and cardiovascular activity in an academic examination
Authors: Gómez‐Íñiguez Consolación , Rodríguez Cristina Guerrero , Cantero Francisco Palmero 
Published: December 2020

AbstractExam is an academic stressor that frequently triggers the affective reaction of anxiety, as well as psychophysiological changes in the autonomic nervous system. Anxiety is a negative affective variable associated with a low level of performance. This study examined the impact of an academic exam on state anxiety (SA) levels and the effects on cardiovascular activity during its performance, as well as its possible influence on the score. The study group was composed of 122 female university students. Cardiovascular responses (heart rate [HR], diastolic blood pressure, and systolic blood pressure) were recorded continuously in three phases (before, during, and after the exam) for each participant. The SA was obtained with the State–Trait Anxiety Inventory (STAI) before the exam. Then, those with extremely low and high SA scores were assigned to the low and high anxiety groups, respectively. The exam score reflected the performance level. The results partially confirmed our hypotheses. The high SA group showed significant fluctuations in cardiovascular activity; in particular, the HRs were higher than in the low SA group during the exam (not in diastolic and systolic pressures, respectively). On the other hand, the high SA group showed lower performance expectations scores than the low SA group, and the level of performance was similar in the two groups. Therefore, the exam confirmed changes in the HR with respect to the SA level, with no significant impact on performance.

AbstractObjectivesTo assess the diagnostic utility of metagenomic sequencing in pediatric aerodigestive clinic patients being evaluated for chronic aspiration. We hypothesize that using a metagenomics platform will aid in the identification of microbes not found on standard culture.Study Design and MethodsTwenty‐four children referred to an aerodigestive clinic were enrolled in a prospective, single‐site, cross‐sectional cohort study. At the time of clinical evaluation under anesthesia, two samples were obtained: an upper airway sample and a sample from bronchoalveolar lavage (BAL). Samples were sent for routine culture and analyzed using Explify® Respiratory, a CLIA Laboratory Developed Test which identifies respiratory commensals and pathogens through RNA and DNA sequencing. Since RNA was sequenced in the course of the metagenomic analysis to identify organisms (RNA viruses and bacteria), the sequencing approach also captured host derived messenger RNA during sample analysis. This incidentally obtained host transcriptomic data were analyzed to evaluate the host immune response. The results of these studies were correlated with the clinical presentation of the research subjects.ResultsIn 10 patients, organisms primarily associated with oral flora were identified in the BAL. Standard culture was negative in three patients where clinical metagenomics led to a result with potential clinical significance. Transcriptomic data correlated with the presence or absence of dysphagia as identified on prior videofluoroscopic evaluation of swallowing.ConclusionsClinical metagenomics allows for simultaneous analysis of the microbiota and the host immune response from BAL samples. As the technologies in this field continue to advance, such testing may improve the diagnostic evaluation of patients with suspected chronic aspiration.

AbstractBACKGROUNDCotton has been increasingly harmed by the mirid bug (Lygus pratensis Linnaeus) in Xinjiang Uyghur Autonomous Region, China. Using trap plants within or around the border of the cotton may be a beneficial management strategy for this pest of cotton.RESULTSThe potential of safflower (Carthamus tinctorius Linn) as a trap plant for managing L. pratensis was evaluated in laboratory and field experiments. Y‐tube olfactometer assays demonstrated that L. pratensis was highly attracted to volatiles derived from safflower. Field experiments showed that safflower plots hosted more L. pratensis (adults and nymphs) than cotton plots. Early‐sown safflower had more L. pratensis than mid‐sown or late‐sown safflower, and was more conducive to the settlement and reproduction of L. pratensis. The density of L. pratensis on safflower trap crops in three sowing patterns was significantly higher than on adjacent cotton. The pattern of intercropping safflower trap crops was more effective at reducing densities of L. pratensis on cotton than placing safflower as ‘spot’ trap crops or peripheral trap crops. However, this result also may be related to the overall area of the safflower trap crops. With regular chemical control of L. pratensis on safflower trap crops, the number of cotton bolls was increased by 10.04%, whereas the rate of boll damage was reduced by 33.44%, compared to cotton without safflower trap crops and insecticide sprays.CONCLUSIONSafflower shows promise as an effective trap crop for L. pratensis, and may contribute to controlling L. pratensis in cotton. © 2020 Society of Chemical Industry

Published: December 2020

AbstractIn recent years, the development of perovskite solar cells (PSCs) is advancing along the way, and the efficiency is comparable to traditional silicon‐based solar cells. However, as crucial factors in the road to commercialization, stability and upscaling manufacture have not been fully investigated yet. To solve these problems, the exploration of charge transport layer (CTL) is clearly imminent, which is critical to the stability of PSCs. Among them, inorganic metal oxides have better stability than organic CTL. Particularly, the atomic layer deposition (ALD) process can fabricate dense and scalable metal oxides based on the self‐limiting surface reaction. This perspective focuses on the recent progress of ALD‐grown metal oxides in PSCs: both of electron and hole transport layer; connection layer in tandem architectures; application in semi‐transparent perovskite solar cells (ST‐PSCs); prospective of commercialization feasibility of the ALD‐grown metal oxides in ST‐PSCs.

AbstractShrinkage of concrete refers to the volumetric change of concrete due to cement hydration (i.e., self‐desiccation) and environmental drying (i.e., water evaporation). It creates dimensional instability and induces tensile stress when the concrete is restrained that may be large enough to cause cracking. The most fundamental way to mitigate concrete shrinkage is to decrease the shrinkage of cementitious paste in the mix design. Some major factors of concrete mix design affecting the shrinkage include water‐to‐cementitious material (W/CM) ratio, dosage of superplasticizer (SP), concrete strength, and cementitious paste volume (CPV). While the effects of concrete strength and CPV on shrinkage are straightforward, those of W/CM and SP are more complicated because they also affect the pore size and distribution that influence the moisture movement. In this paper, it is advocated to study the concrete shrinkage by its wet packing density (WPD). Considering that the shrinkage of concrete is associated with the moisture movement in capillary pores and that the WPD accounts for the void ratio in fresh concrete, it will be shown in this paper that the shrinkage can be correlated negatively to the WPD with the consideration of CPV. The paper thus provides a new insight to the interdependence amongst shrinkage, CPV, and WPD of concrete.
Early embryonic exposure to chlorpyrifos‐cypermethrin combination induces pattern deficits in the heart of domestic hen

AbstractExposure to chlorpyrifos‐cypermethrin combination during early development resulted in defective looping and ventricular noncompaction of heart in domestic chicken. The study was extended to elucidate the molecular basis of this novel observation. The primary culture of chicken embryonic heart cells showed a concentration‐dependent loss of viability when challenged with this combination of technical‐grade insecticides. Comet assay, DNA ladder assay, and analyses of appropriate markers at transcript and protein levels, revealed that chlorpyrifos‐cypermethrin combination induced cell death by activating apoptosis. Parallelly, the tissues derived from control and experimental group hearts were checked for apoptotic markers, and the result was much similar to that of the in‐vitro study. Further analysis showed that chlorpyrifos‐cypermethrin combination deranged the expression pattern of the transcriptional regulators of cardiogenesis, namely TBX20, GATA5, HAND2, and MYOCD. This, together with heightened apoptosis, could well be the reason behind the observed structural anomalies in the heart of chlorpyrifos‐cypermethrin poisoned embryos.
A non‐radioactive DNA synthesis assay demonstrates that elements of the Sigma 1278b Mip1 mitochondrial DNA polymerase domain and C‐terminal extension facilitate robust enzyme activity

Published: December 2020

AbstractThe yeast DNA polymerase gamma, Mip1, is a useful tool to investigate the impact of orthologous human disease variants on mitochondrial DNA (mtDNA) replication. However, Mip1 is characterized by a C‐terminal extension (CTE) that is not found on orthologous metazoan DNA polymerases, and the CTE is required for robust enzymatic activity. Two MIP1 alleles exist in standard yeast strains, encoding Mip1[S] or Mip1[Σ]. Mip1[S] is associated with reduced mtDNA stability and increased error rates in vivo. Although the Mip1[S] allele was initially identified in S288c, the Mip1[Σ] allele is widely present among available yeast genome sequences, suggesting that it is the wild‐type (WT) allele. We developed a novel non‐radioactive polymerase gamma assay to assess Mip1 functioning at its intracellular location, the mitochondrial membrane. Membrane fractions were isolated from yeast cells expressing full‐length or CTE truncation variants of Mip1[S] or a chimeric Mip1[S] isoform harboring the Mip1[Σ]‐specific T661 residue (cMip1 T661). Relative incorporation of digoxigenin (DIG)‐11‐deoxyuridine monophosphate (DIG‐dUMP) by cMip1 T661 was higher than that by Mip1[S]. A cMip1 T661variant lacking 175 C‐terminal residues maintained WT levels of DIG‐dUMP incorporation, whereas the C‐terminal variant lacking 205 residues displayed a significant decrease in incorporation. Newly synthesized DIG‐labeled DNA decreased during later phases of reactions carried out at 37°C, suggesting temperature‐sensitive destabilization of the polymerase domain and/or increased shuttling of the nascent DNA into the exonuclease domain. Comparative analysis of Mip1 enzyme functions using our novel assay has further demonstrated the importance of the CTE and T661 encoded by MIP1[Σ] in yeast mtDNA replication.
Safety Aboard Chinese Vessels
Authors: Xue Conghua 
Published: December 2020

AbstractThe aim of this chapter is to explore the factors that affect ship to shore safety reporting in the Chinese shipping industry. The study was motivated by of the paucity of research in this specific area. Previous research in shore-based industries suggests that there may be cause for concern in shipping as ashore there is evidence of significant underreporting across a wide range of industries. This study, though it is small in scale, was conducted to partially fill the existing gap. The data used was collected from two major chemical shipping companies in China. Both employers and employees’ perspectives were considered in the process of data analysis. Furthermore, the ‘social factors’ behind the scene of reporting—underreporting, or biased reporting—were explored.
Union Organising in the Context of Regional Labour Market Decline: The Case of Nautilus International
Authors: Gekara Victor Oyaro 
Published: December 2020

AbstractOver the past few decades the impact of globalisation on society and industry at the national level has been immense and has been studied and extensively documented in the literature. Some of the major benefits and losses accruing from economic globalisation, particularly since the late 1970s have been debated by dominant political economy commentators (see e.g. Harvey 2005; Held et al. 1999; Strange 1996; Scholte 2000; Stiglitz 2002; Giddens 2002; Chomsky 2017). An important aspect of the globalising process has been the extensive restructuring of production and distribution patterns in search of cheaper resources, through aggressive outsourcing and offshoring. The result for many national economies, particularly advanced industrial states, has been a drastic decline in traditional industries affecting both labour and capital (Dunning 1993; Beck 2005; Perraton 2019). This chapter examines the decline in the seafaring labour markets of the so-called Traditional Maritime Countries (TMN), and the implications for union organising focusing on the UK and its seafaring labour. It examines the creation of Nautilus International (NI) Union via a merger of unions for maritime professionals across different countries in Europe initially beginning with Great Britain, the Netherlands and later Switzerland. This was a uniquely strategic response to declining membership and weakening organising capacity. Some of the key challenges associated with unions trying to organise and represent their members in the context of industrial and labour market decline are explored.
On-Line Support Groups for Families in China
Authors: Tang Lijun 
Published: December 2020

AbstractSeafarer-partners (seafarers’ wives or girlfriends) face a number of problems in everyday life, including consecutive long-term separations and social isolation. In the context that seafaring families are likely to be geographically dispersed, a virtual community provided Chinese seafarer-partners with a valuable space to talk about problems and to both offer and receive support. Despite the physical distances between community members they felt closely connected to each other in the community because they were all seafarer-partners and had similar concerns and experiences. By examining their interaction in this community, the chapter reveals the ways in which this virtual community may offer, essential, largely unseen, informal, support to seafarers by serving to protect their very vulnerable relationships in their absence.
Careers at Sea: Exploring Seafarer Motivations and Aspirations
Authors: Baum-Talmor Polina 
Published: December 2020

AbstractNowadays, in the era of flexible and precarious employment, the concept of a ‘career for life’ in one organisation appears to be redundant, as most employees in the global labour market do not have permanent employment (ILO, World employment and social outlook: the changing nature of jobs. Geneva: International Labour Office, 2015). This chapter focuses on the shipping industry as an example of a global industry that employs over a million seafarers (BIMCO, Manpower 2005 update: the worldwide demand for and supply of seafarers. Warwick: Warwick Institute for Employment Research, 2015) as their main labour force in what could termed flexible employment. The chapter explores the idea of having a ‘career’ within the precarious shipping industry by focusing on the reasons for joining, staying, and leaving a seafaring occupation. The chapter is based on existing literature, and on recent data that was collected as part of a study on seafarers’ career development.
Learn to Lead: Developing Curricula that Foster Climate Change Leaders
Authors: Rhodes David , Wang Margaret 
Published: December 2020

AbstractIn this chapter, we identify the need for a curriculum that is intended to not only enable educators to teach about climate change, but to also foster leaders who can engage in policy analysis and civic action related to the issue of climate change. Unlike Chap. 3, which details a whole-school approach, we have specifically focused our attention on developing a curriculum with an associated implementation plan since the ability of teachers to build transferable leadership skills in younger generations are integral to any larger reform initiative. Ultimately, the efficacy of the curriculum is enhanced by a more holistic approach to the prioritization of climate change action in the context of schools and broader education systems, so a synthesis of approaches is recommended.The Climate Change Leadership Curriculum was designed in collaboration with the Arava Institute (AI), an organization in Israel that brings together Israelis, Palestinians, Jordanians and international students from outside the region to engage in environmental and peace-building education. The work of AI is specific to tertiary education, so our initiative to build a climate change leadership curriculum constitutes an attempt to expand the reach of the mission and pedagogy of AI to encompass secondary education. The implementation plan also involves leveraging the network of AI to find partners for implementing the curriculum. The fact that there are AI alumni who work in secondary education opened possibilities for dissemination of the curriculum in collaboration with teachers who have a deep understanding of the pedagogy. As teachers integrate the curriculum into their particular contexts, our plan was to not only support them in the implementation, but to also solicit feedback to continually improve the resources and identify the most effective ways to provide support. This will enable us to make the curriculum accessible to teachers from diverse backgrounds in a wide variety of contexts, inside and outside of the target region.
Creating a Culture of Shared Responsibility for Climate Action in Guatemala Through Education
Authors: Lopez Lalinde Lina , Maierhofer Carrie 
Published: December 2020

AbstractGuatemala is a country particularly susceptible to the effects of climate change. Residents of the country are increasingly experiencing frequent natural hazards, witnessing rising temperatures, and grappling with maintaining sources of income and nutrition. For these and other reasons, it is crucial that Guatemalans have access to effective climate change education in order to be equipped with the skills and knowledge necessary to appropriately adapt to and mitigate the effects of climate change in their communities. With Atitlán Multicultural Academy, a K-12 school located in Guatemala’s Western Highlands, as our pilot school, we have created the blueprint for a region-specific guidebook focused on incorporating the spirit of climate action into the areas of leadership, curriculum, community partnerships, and professional development within the school. It is our hope that this guidebook can continually be adjusted and made relevant for schools around the globe as they work to create a culture of shared responsibility for climate action.
