Identifying information need through storytelling
Authors: Barefoot Maria R. 
Published: July 2018

Purpose
The purpose of this paper is to explore the use of multicultural narratives from the website Humans of New York in a one credit information literacy course to teach concepts of information need with respect to cultural literacy and social justice.

Design/methodology/approach
This case study examines student responses to an in-class activity which used a problem-based learning approach. Students were asked to examine narratives and identify possible information access or use issues and to consider the cultural differences that may help or hinder information access or use.

Findings
Students’ writing samples show evidence of comprehension in the areas of cultural literacy and understanding information need and the development empathy with people of diverse racial, cultural and socioeconomic backgrounds. Students directly identified information need issues such as financial barriers, social stigma, lack of access to legal aid and the risk of physical harm. Students indirectly recognized concepts related to cultural literacy and social justice such as cultural norms, classism and structural racism.

Originality/value
While the Framework for Information Literacy for Higher Education has listed a number of social justice and cultural literacy concepts within the knowledge practices and disposition statements, the library literature has not yet studied these concepts in conjunction with teaching information need. This case study presents a lesson plan that could be applied in library classrooms to teach both cultural literacy and information need concepts.
Communicating a social agenda within HEIs: the role of the social enterprise mark
Authors: Sutton Emma , McEachern Morven , Kane Kevin 
Published: July 2018

Purpose
By using the lens of the social enterprise mark (SEM) accreditation which enables social enterprises to “prove” that the interests of people and planet are put before shareholder gain, this study aims to enhance the knowledge of how effectively the social agenda is communicated by higher education institutions (HEIs).

Design/methodology/approach
By using a qualitative research design, this exploratory study uses a combination of both a focus group and in-depth interviews with HEI holders of the SEM.

Findings
With a particular focus on University A, this study advances the knowledge around how social agendas and the role of the SEM in particular are used to communicate to HEI employees as a key stakeholder group.

Research limitations/implications
At the time of this study, fewer SEM accredited HEIs existed, and therefore, the following conclusions are based upon a small select sample of HEIs that held the SEM. Further studies are needed to provide a more representative view of each university’s use of and commitment to the SEM/ Social Enterprise Gold Mark.

Practical implications
Building on Powell and Osborne’s (2015) observations regarding the role of marketing in social enterprises, the findings of this study offer practical insight into current and or prospective HEI SEM holders as to the role of “social” accreditations, stakeholder perceptions of such marketing initiatives and how they can be used as a vehicle to improve social communications in the future.

Originality/value
The area of social enterprise and social impact has been evolving in recent decades, but literature in relation to its promotion and communication in the higher education sector remains scant. This study responds to this gap in the literature by providing greater insight into how social agendas and engagement with the SEM, specifically, are communicated by HEIs.
Quality in higher education institutions: insights from the literature
Authors: Prakash Gyan 
Published: July 2018

Purpose
The purpose of this paper is to understand the meaning and operationalisation of quality in the context of higher education institutions (HEIs).

Design/methodology/approach
A systematic literature review is performed of 308 articles published in various peer-reviewed journals between 1999 and 2017.

Findings
The findings reveal that the quality constructs of student learning, engagement, service quality and satisfaction have received the greatest attention, followed by total quality management, quality assurance, benchmarking and accountability. The most popular approach is empirical, and surveys and single case studies are the most popular methods. Europe leads research on quality in HEIs, followed by North America and Asia.

Research limitations/implications
This paper contributes to the body of knowledge by presenting a comprehensive synthesis of articles addressing quality in HEIs.

Practical implications
Policymakers and academic administrators can use the findings of this study to conceptualise student satisfaction along the educational value chain. The operationalisation of quality constructs will help policymakers create teaching excellence.

Originality/value
This paper highlights the importance of quality in HEIs.

Abstract

Once established in new areas, introduced species may exhibit changes in their biology due to phenotypic plasticity, novel selection pressures and genetic drift. Moreover, the introduction process itself has been hypothesised to act as a selective filter for traits that promote invasiveness.

We tested the hypothesis that behaviours thought to promote invasiveness—such as increased foraging activity and aggression—are selected for during invasion by comparing traits among native and introduced populations of the widespread Argentine ant (Linepithema humile).

We studied Argentine ant populations in the native range in Argentina and in three invaded regions along an introduction pathway: California, Australia and New Zealand. In each region, we set up 32 experimental colonies to measure foraging activity and interspecific aggression in a subset of the study regions. These colonies were subject to experimental manipulation of carbohydrate availability and octopamine, a biogenic amine known to modulate behaviour in insects, to measure variation in behavioural plasticity.

We found variation in foraging activity among populations, but this variation was not consistent with selection on behaviour in relation to the invasion process. We found that colonies with limited access to carbohydrates exhibited unchanged exploratory behaviour, but higher exploitation activity and lower aggression. Colonies given octopamine consistently increased foraging behaviour (both exploration and exploitation), as well as aggression when also sugar‐deprived. There was no difference in the degree of behavioural response to our experimental treatments along the introduction pathway.

We did not find support for selection of behavioural traits associated with invasiveness along the Argentine ant's introduction pathway or clear evidence for an association between the introduction process and variation in behavioural plasticity. These results indicate that mechanisms promote behavioural variation in a similar fashion both in native and introduced ranges. Our results challenge the assumption that introduced populations always perform better in key behavioural traits hypothesised to be associated with invasion success.
Distinct molecular signatures in dissolved organic matter produced by viral lysis of marine cyanobacteria
Authors: Ma Xiufeng , Coleman Maureen L. , Waldbauer Jacob R. 
Published: July 2018

SummaryDissolved organic matter (DOM) plays a central role in the microbial ecology and biogeochemistry of aquatic environments, yet little is known about how the mechanism of DOM release from its ultimate source, primary producer biomass, affects the molecular composition of the inputs to the dissolved pool. Here we used a model marine phytoplankton, the picocyanobacterium Synechococcus WH7803, to compare the composition of DOM released by three mechanisms: exudation, mechanical cell lysis and infection by the lytic phage S‐SM1. A broad, untargeted analytical approach reveals the complexity of this freshly sourced DOM, and comparative analysis between DOM produced by the different mechanisms suggests that exudation and viral lysis are sources of unsaturated, oxygen‐rich and possibly novel biomolecules. Furthermore, viral lysis of WH7803 by S‐SM1 releases abundant peptides derived from specific proteolysis of the major light‐harvesting protein phycoerythrin, raising the possibility that phage infection of these abundant cyanobacteria could be a significant source of high molecular weight dissolved organic nitrogen compounds.
Set1 and Kdm5 are antagonists for H3K4 methylation and regulators of the major conidiation‐specific transcription factor gene ABA1 in Fusarium fujikuroi
Authors: Janevska Slavica , Güldener Ulrich , Sulyok Michael , Tudzynski Bettina , Studt Lena 
Published: July 2018

SummaryHere we present the identification and characterization of the H3K4‐specific histone methyltransferase Set1 and its counterpart, the Jumonji C demethylase Kdm5, in the rice pathogen Fusarium fujikuroi. While Set1 is responsible for all detectable H3K4me2/me3 in this fungus, Kdm5 antagonizes the H3K4me3 mark. Notably, deletion of both SET1 and KDM5 mainly resulted in the upregulation of genome‐wide transcription, also affecting a large set of secondary metabolite (SM) key genes. Although H3K4 methylation is a hallmark of actively transcribed euchromatin, several SM gene clusters located in subtelomeric regions were affected by Set1 and Kdm5. While the regulation of many of them is likely indirect, H3K4me2 levels at gibberellic acid (GA) genes correlated with GA biosynthesis in the wild type, Δkdm5 and OE::KDM5 under inducing conditions. Whereas Δset1 showed an abolished GA3 production in axenic culture, phytohormone biosynthesis was induced in planta, so that residual amounts of GA3 were detected during rice infection. Accordingly, Δset1 exhibited a strongly attenuated, though not abolished, virulence on rice. Apart from regulating secondary metabolism, Set1 and Kdm5 function as activator and repressor of conidiation respectively. They antagonistically regulate H3K4me3 levels and expression of the major conidiation‐specific transcription factor gene ABA1 in F. fujikuroi.
Comparative genomics of a quadripartite symbiosis in a planthopper host reveals the origins and rearranged nutritional responsibilities of anciently diverged bacterial lineages
Authors: Bennett Gordon M. , Mao Meng 
Published: July 2018

SummaryInsects in the Auchenorrhyncha (Hemiptera: Suborder) established nutritional symbioses with bacteria approximately 300 million years ago (MYA). The suborder split early during its diversification (~ 250 MYA) into the Fulgoroidea (planthoppers) and Cicadomorpha (leafhoppers and cicadas). The two lineages share some symbionts, including Sulcia and possibly a Betaproteobacteria that collaboratively provide their hosts with 10 essential amino acids (EAA). Some hosts harbour three bacteria, as is common among planthoppers. However, genomic studies are currently restricted to the dual‐bacterial symbioses found in Cicadomorpha, leaving the origins and functions of these more complex symbioses unclear. To address these questions, we sequenced the genomes and performed phylogenomic analyses of ‘Candidatus Sulcia muelleri’ (Bacteroidetes), ‘Ca. Vidania fulgoroideae’ (Betaproteobacteria) and ‘Ca. Purcelliella pentastirinorum’ (Gammaproteobacteria) from a planthopper (Cixiidae: Oliarus). In contrast to the Cicadomorpha, nutritional synthesis responsibilities are rearranged between the cixiid symbionts. Although Sulcia has a highly conserved genome across the Auchenorrhyncha, in the cixiids it is greatly reduced and provides only three EAAs. Vidania contributes the remaining seven EAAs. Phylogenomic results suggest that it represents an ancient symbiont lineage paired with Sulcia throughout the Auchenorrhyncha. Finally, Purcelliella was recently acquired from plant‐insect associated bacteria (Pantoea‐Erwinia) to provide B vitamins and metabolic support to its degenerate partners.
Plant‐Derived Substances Used Against Beetles–Pests of Stored Crops and Food–and Their Mode of Action: A Review
Authors: Spochacz Marta , Chowański Szymon , Walkowiak‐Nowicka Karolina , Szymczak Monika , Adamski Zbigniew 
Published: July 2018

AbstractPlants are sources of numerous active substances that are used to protect crops. Currently, due to the limitations of using synthetic insecticides, plant products have attracted increasing attention as possible pesticides. In this review, we discuss some of the most interesting plant products (for example, Solanaceae, or Asteraceae extracts,Artemisia absinthiumorCitrus spp. essential oils, and single compounds like α‐chaconine, or α‐solanine) that exhibit insecticidal activity against beetles that are pests of stored food products. Next, we describe and discuss the mode of action of these products, including lethal and sublethal effects, such as antifeedant or neurotoxic activity, ultrastructural malformation, and effects on prooxidant/antioxidant balance. Furthermore, the methods of application of plant‐derived substances in food storage areas are presented.

Published: July 2018

SummaryThe loggerhead sea turtle (Caretta caretta) is the most widespread sea turtle species in the Mediterranean Sea and a relevant pollution ‘flagship species’. Here, we profiled the faecal microbiota from 29 C. caretta from a rescue centre, and explored the impact of several variables linked to both the animal itself and the environment (i.e., tank water ecosystem). We show that loggerhead turtles share more gut microbiota features with carnivorous marine mammals, than with phylogenetically close, but herbivorous, turtles, as a confirmation of the gut microbiota adaptive function to diet and environment. We also highlight a relation between the microbiota composition and the size (and consequently the age) of the turtles. Finally, we point out that the gut microbiota of sea turtles shows unexpectedly low exchange of microbes with the aquatic environment and is resilient to the stress induced by short‐time captivity.
Macrobenthic communities at high southern latitudes: Food supply for long‐distance migratory shorebirds
Authors: Micael Joana , Navedo Juan G. 
Published: July 2018

AbstractIntertidal soft‐bottom assemblages located at high latitudes provide a critical food source for long‐distance migratory animals which link biodiversity across distant areas. On the southern Pacific coasts of South America, however, comprehensive information about macrobenthic assemblages at these habitats is lacking. Here we provide an inter‐annual estimation of food supply at the southern limit of the Pacific temperate zone within a Site of Hemispheric Importance for the conservation of Arctic breeding shorebird populations during the nonbreeding season. Macrobenthic communities on Isla Grande of Chiloé are dominated by Polychaetes, Bivalves and Malacostraca. Average biomass (4.4–9.6 g ash‐free dry weight m−2) falls within the values reported for temperate intertidal areas located at around 40°S latitude. While total available biomass within each bay was similar during the three sampling years, the annual contribution of each class varied. The major contributor to zoobenthic biomass (Polychaetes) was indeed one of the main preys for the most abundant shorebird species at Chiloé. Arctic breeding migratory shorebird populations seem thus to encounter a predictable and abundant food supply at high southern latitudes on Isla Grande of Chiloé.
Diagnostic point‐of‐care ultrasound: applications in obstetric anaesthetic management

Published: July 2018

SummaryComplications during pregnancy are not frequent, but may occur abruptly. Point‐of‐care ultrasound is a non‐invasive, non‐ionising diagnostic tool that is available at the bed‐side when complications occur. This review covers the use of ultrasound in various clinical situations. Gastric ultrasound can identify stomach contents that put the woman at risk for pulmonary aspiration. In the future, this tool will probably be used routinely before induction of anaesthesia to determine the presence of stomach contents above a particular risk threshold. Difficult tracheal intubation, and the potential for ‘can't intubate, can't oxygenate’, is more frequent in pregnant women. Point‐of‐care ultrasound of the airway allows accurate identification of the cricothyroid membrane, permitting rapid and safer establishment of front‐of‐neck airway access. Combined cardiac and lung ultrasound can determine the potential risk:benefit of fluid administration in the pregnant patient. Such prediction is of critical importance, given the tendency of pregnant women to develop pulmonary oedema. Combined echocardiography and lung ultrasound can be combined with ultrasound of the leg veins to differentiate between the various causes of acute respiratory failure, and guide treatment in this situation. Finally, as shown in the general population, multi‐organ point‐of‐care ultrasound allows early diagnosis of the main causes of circulatory failure and cardiac arrest at the bed‐side. As the importance of point‐of‐care ultrasound in critical patients is increasingly recognised, it is emerging as an important tool in the therapeutic armoury of obstetric anaesthetists.
The Dark Side of Transformation: Latent Risks in Contemporary Sustainability Discourse

Published: July 2018

AbstractThe notion of transformation is gaining traction in contemporary sustainability debates. New ways of theorising and supporting transformations are emerging and, so the argument goes, opening exciting spaces to (re)imagine and (re)structure radically different futures. Yet, questions remain about how the term is being translated from an academic concept into an assemblage of normative policies and practices, and how this process might shape social, political, and environmental change. Motivated by these questions, we identify five latent risks associated with discourse that frames transformation as apolitical and/or inevitable. We refer to these risks as the dark side of transformation. While we cannot predict the future of radical transformations towards sustainability, we suggest that scientists, policymakers, and practitioners need to consider such change in more inherently plural and political ways.
A Political Ontology of Land: Rooting Syrian Identity in the Occupied Golan Heights
Authors: Mason Michael , Dajani Muna 
Published: July 2018

AbstractQuestions of identity, belonging and place are heightened in societies under protracted military occupation. Bridging scholarship on territorial justice and settler colonialism, this paper examines the impacts of, and responses to, the misrecognition of Arab residents enacted by the Israeli state in the occupied Golan Heights. The injustice of misrecognition entails the imposition on the indigenous population of a Zionist ethnogeography consolidated through Jewish settlements, forced citizenship and discriminatory land and water policies. Focusing on the distinctive agricultural practices by which a Jawlani (Syrian Golani) identity is forged, we highlight the role of sumud (“steadfastness”) as a strategy of non‐violent resistance. Sumud here rests on the mobilisation of communal norms of land and water management, evident in the creation of counter‐infrastructures and water collectives supporting apple orchards. In the face of settler colonial misrecognition, Jawlani rootedness expresses a distinctive ontology on land with a conjoined right of resourcehood.

SummaryBackgroundThe incidence of hepatocellular carcinoma (HCC) in patients with a history of curatively‐treated HCC is higher than in patients with no history of HCC even after sustained virologic response (SVR).AimTo investigate differences in the patterns of HCC development after SVR in patients with a history of curatively‐treated HCC and those with no history of HCC, based on gadolinium‐ethoxybenzyl‐diethylenetriamine pentaacetic acid‐enhanced magnetic resonance imaging (EOB‐MRI) findings.MethodsEOB‐MRI was performed in 164 patients with HCV cirrhosis who achieved SVR by interferon‐free direct‐acting antiviral (DAA) therapy just before the start of therapy. Changes in EOB‐MRI findings after SVR were compared prospectively between patients with (n = 62) and without (n = 102) a history of HCC.ResultsThe incidence of HCC after SVR was higher in patients with a history of HCC (P < 0.0001). The prevalence of nonhypervascular hypointense nodules (NHHNs) by EOB‐MRI was significantly higher in patients with a history of HCC at baseline (P = 0.05). Although there was no difference in the incidence of the hypervascularisation of baseline NHHNs to typical hypervascular HCC between patients with and without a history of HCC, the incidence of direct emergence of hypervascular HCC despite the absence of NHHNs at baseline was significantly higher in patients with a history of HCC (P < 0.0001).ConclusionDirect emergence of hypervascular HCC and a higher prevalence of NHHNs before DD therapy contributed to the higher incidence of HCC after SVR.

AimsThis study aimed to determine the effect of food intake on uracil and dihydrouracil plasma levels. These levels are a promising marker for dihydropyrimidine dehydrogenase activity and for individualizing fluoropyrimidine anticancer therapy.MethodsA randomized, cross‐over study in 16 healthy volunteers was performed, in which subjects were examined in fasted and fed state on two separate days. In fed condition, a high‐fat, high‐caloric breakfast was consumed between 8:00 h and 8:30 h. Whole blood for determination of uracil, dihydrouracil and uridine plasma levels was drawn on both test days at predefined time points between 8:00 h and 13:00 h.ResultsUracil levels were statistically significantly different between fasting and fed state. At 13:00 h, the mean uracil level in fasting state was 12.6 ± 3.7 ng ml−1 and after a test meal 9.4 ± 2.6 ng ml−1 (P < 0.001). Dihydrouracil levels were influenced by food intake as well (mean dihydrouracil level at 13:00 h in fasting state 147.0 ± 36.4 ng ml−1 and in fed state 85.7 ± 22.1 ng ml−1, P < 0.001). Uridine plasma levels showed curves with similar patterns as for uracil.ConclusionsIt was shown that both uracil and dihydrouracil levels were higher in fasting state than in fed state. This is hypothesized to be an direct effect of uridine plasma levels, which were previously shown to be elevated in fasting state and reduced after intake of food. These findings show that, when assessing plasma uracil and dihydrouracil levels for adaptive fluoropyrimidine dosing in clinical practice, sampling should be done between 8:00 h and 9:00 h after overnight fasting to avoid bias caused by circadian rhythm and food effects.
