Lessons learned
Authors: Michell Vaughan , McKenzie Jane 
Published: July 2017

Purpose
To increase the spread and reuse of lessons learned (LLs), the purpose of this paper is to develop a standardised information structure to facilitate concise capture of the critical elements needed to engage secondary learners and help them apply lessons to their contexts.

Design/methodology/approach
Three workshops with industry practitioners, an analysis of over 60 actual lessons from private and public sector organisations and seven practitioner interviews provided evidence of actual practice. Design science was used to develop a repeatable/consistent information model of LL content/structure. Workshop analysis and theory provided the coding template. Situation theory and normative analysis were used to define the knowledge and rule logic to standardise fields.

Findings
Comparing evidence from practice against theoretical prescriptions in the literature highlighted important enhancements to the standard LL model. These were a consistent/concise rule and context structure, appropriate emotional language, reuse and control criteria to ensure lessons were transferrable and reusable in new situations.

Research limitations/implications
Findings are based on a limited sample. Long-term benefits of standardisation and use need further research. A larger sample/longitudinal usage study is planned.

Practical implications
The implementation of the LL structure was well-received in one government user site and other industry user sites are pending. Practitioners validated the design logic for improving capture and reuse of lessons to render them easily translatable to a new learner’s context.

Originality/value
The new LL structure is uniquely grounded in user needs, developed from existing best practice and is an original application of normative and situation theory to provide consistent rule logic for context/content structure.

Abstract

Poaching is one of the greatest threats to wildlife conservation world‐wide. However, the spatial and temporal patterns of poaching activities within protected areas, and the effectiveness of ranger patrols and ranger posts in mitigating these threats, are relatively unknown.

We used 10 years (2006–2015) of ranger‐based monitoring data and dynamic multi‐season occupancy models to quantify poaching‐related threats, to examine factors influencing the spatio‐temporal dynamics of these threats and to test the efficiency of management actions to combat poaching in Nyungwe National Park (NNP), Rwanda.

The probability of occurrence of poaching‐related threats was highest at lower elevations (1,801–2,200 m), especially in areas that were close to roads and tourist trails; conversely, occurrence probability was lowest at high elevation sites (2,601–3,000 m), and near the park boundary and ranger posts. The number of ranger patrols substantially increased the probability that poaching‐related threats disappear at a site if threats were originally present (i.e. probability of extinction of threats). Without ranger visits, the annual probability of extinction of poaching‐related threats was an estimated 7%; this probability would increase to 20% and 57% with 20 and 50 ranger visits per year, respectively.

Our results suggest that poaching‐related threats can be effectively reduced in NNP by adding ranger posts in areas where they do not currently exist, and by increasing the number of patrols to sites where the probability of poaching activities is high.

Synthesis and applications. Our application of dynamic occupancy models to predict the probability of presence of poaching‐related threats is novel, and explicitly considers imperfect detection of illegal activities. Based on the modelled relationships, we identify areas that are most vulnerable to poaching, and offer insights regarding how ranger patrols can be optimally deployed to reduce poaching‐related threats and other illegal activites, while taking into account potential sampling biases. We show that poaching can be effectively reduced by increasing ranger patrols to areas under high risk of poaching activities, and by adding ranger patrols near these sites. These findings are broadly applicable to national parks and protected areas experiencing a high degree of poaching and other illegal activities.

Published: July 2017

AimThe aim of the present study was to determine if the Malnutrition Screening Tool (MST) is valid for use within the Community Rehabilitation Program (CRP) setting. Secondary outcome measures were to assess malnutrition prevalence in the CRP population and to determine trends between malnutrition and age, body mass index (BMI) and falls history.MethodsThis study used a cross‐sectional design. All clients admitted to a Melbourne metropolitan CRP during the study period had the MST completed at intake. A total of 160 participants were then selected at random and a Subjective Global Assessment (SGA) was completed by an experienced dietitian. Participants were classified as well nourished or malnourished, and this result was compared to their MST score. Data analysis was completed to determine the predictive value of the MST compared to SGA, which was expressed using sensitivity, specificity, positive and negative predictive values.ResultsOut of the 160 participants, 34.0% were identified as malnourished. The MST achieved a sensitivity of 72.2% and a specificity of 83.8% with positive predictive value of 69.6% and negative predictive value of 85.4% compared to the SGA. Participants in the malnourished group were older and had a lower BMI (P < 0.05).ConclusionsConsidering the demographics and needs of the CRP population group and the predictive value of the MST compared to SGA, it can be concluded that the MST is a valid screening tool for use in this population and has relatively low burden to complete. Consequently, the MST could be included in the client initial needs identification to be completed when admitted to the program.
Disruptive physiology: olfaction and the microbiome–gut–brain axis
Authors: Bienenstock John , Kunze Wolfgang A. , Forsythe Paul 
Published: July 2017

ABSTRACTThis review covers the field of olfaction and chemosensation of odorants and puts this information into the context of interactions between microbes and behaviour; the microbiome–gut–brain axis (MGBA). Recent emphasis has also been placed on the concept of the holobiome which states that no single aspect of an organism should be viewed separately and thus must include examination of their associated microbial populations and their influence. While it is known that the microbiome may be involved in the modulation of animal behaviour, there has been little systematized effort to incorporate into such studies the rapidly developing knowledge of the wide range of olfactory systems.The classical olfactory system is evolutionarily conserved in multiple taxa from insects through to fish, reptiles and mammals, and is represented by the largest gene families in vertebrates. Mice have over 1000 different olfactory receptors and humans about 400. They are distributed throughout the body and are even found in spermatozoa where they function in chemotaxis. Each olfactory receptor has the unique functional capability of high‐affinity binding to several different molecular ligands. These and other properties render the cataloguing of odorants (odorome) with specific actions a difficult task. Some ectopic olfactory receptors have been shown to have functional effects in the gut and kidney, highlighting the complexity of the systems engaged by odorants. However, there are, in addition to classical olfactory receptors, at least two other families of receptors involved in olfaction that are also widely found expressed on tissues in many different organs in addition to the nervous system and brain: the trace‐amine associated and formyl peptide receptors.Bacteria can make many if not most odorants and are responsible for recognition of species and relative relatedness, as well as predator presence, among many other examples. Activation of different combinations of olfactory receptors by bacterial products such as β‐phenylethylamine have been shown even to control expression of emotions such as fear and aggression. The number of examples of bacterial products and volatile odorants influencing brain function and behaviour is expanding rapidly. Since it is recognized that many different bacterial products and metabolites also function as social cues, and may themselves be directly or indirectly causative of behavioural change, it becomes ever more important to include olfaction into studies of the MGBA. Clearly there are broader implications for the involvement of olfaction in this rapidly evolving field. These include improvement in our understanding of the pathways engaged in various behaviours, and the identification of novel approaches and new targets in efforts to modulate behavioural changes.

AbstractGeographic isolation is the first step in insect herbivore diet specialization. Such specialization is postulated to increase insect fitness, but may simultaneously reduce insect ability to colonize novel hosts. During the Paleocene‐Eocene, plants from the order Zingiberales became isolated either in the Paleotropics or in the Neotropics. During the Cretaceous, rolled‐leaf beetles diversified in the Neotropics concurrently with Neotropical Zingiberales. Using a community of Costa Rican rolled‐leaf beetles and their Zingiberales host plants as study system, we explored if previous geographic isolation precludes insects to expand their diets to exotic hosts. We recorded interactions between rolled‐leaf beetles and native Zingiberales by combining DNA barcodes and field records for 7450 beetles feeding on 3202 host plants. To determine phylogenetic patterns of diet expansions, we established 20 experimental plots in the field, in which we planted plots five exotic Zingiberales, recording beetles feeding on these exotic hosts. In the laboratory, using both native and exotic host plants, we reared a subset of insect species that had expanded their diets to the exotic plants. The original plant–herbivore community comprised 24 beetle species feeding on 35 native hosts, representing 103 plant–herbivore interactions. After exotic host plant introduction, 20 percent of the beetle species expanded their diets to exotic Zingiberales. Insects only established on exotic hosts that belong to the same plant family as their native hosts. Laboratory experiments show that beetles are able to complete development on these novel hosts. In conclusion, rolled‐leaf beetles are preadapted to expand their diets to novel host plants even after millions of years of geographic isolation.
Hydraulics link leaf shape and environmental niche in terrestrial bromeliads
Authors: Males Jamie 
Published: July 2017

AbstractTerrestrial species of the megadiverse bromeliad family display a wide variety of leaf shapes, many of which have evolved convergently in different lineages. Here, I examine the links between leaf shape, venation architecture, hydraulic function, and bioclimatic relations in two bromeliad groups displaying diverse leaf shapes, the genus Pitcairnia (Pitcairnioideae) and the terrestrial grade of the Bromelioideae subfamily. Leaf shapes with broader leaf blades, notably petiolate and lanceolate morphologies, tend to show wider vein spacing, which is associated with reduced hydraulic capacity and higher hydraulic vulnerability. In turn, these leaf shapes tend to occur in species restricted to moist, aseasonal environments, suggesting that hydraulic function is an important mediator of the relationship between leaf shape and bromeliad environmental niches. This network of trait–trait and trait–environment relationships may have been of profound important in the ecological and evolutionary diversification of the bromeliads. Similar structure–function principles are likely to apply in other tropical herbaceous monocots, which are of great ecological importance but generally neglected in plant hydraulic research.
Nested Tracking Graphs

Published: July 2017

AbstractTracking graphs are a well established tool in topological analysis to visualize the evolution of components and their properties over time, i.e., when components appear, disappear, merge, and split. However, tracking graphs are limited to a single level threshold and the graphs may vary substantially even under small changes to the threshold. To examine the evolution of features for varying levels, users have to compare multiple tracking graphs without a direct visual link between them. We propose a novel, interactive, nested graph visualization based on the fact that the tracked superlevel set components for different levels are related to each other through their nesting hierarchy. This approach allows us to set multiple tracking graphs in context to each other and enables users to effectively follow the evolution of components for different levels simultaneously. We demonstrate the effectiveness of our approach on datasets from finite pointset methods, computational fluid dynamics, and cosmology simulations.
Empirically Measuring Soft Knowledge in Visualization
Authors: Kijmongkolchai Natchaya , Abdul‐Rahman Alfie , Chen Min 
Published: July 2017

AbstractIn this paper, we present an empirical study designed to evaluate the hypothesis that humans’ soft knowledge can enhance the cost‐benefit ratio of a visualization process by reducing the potential distortion. In particular, we focused on the impact of three classes of soft knowledge: (i) knowledge about application contexts, (ii) knowledge about the patterns to be observed (i.e., in relation to visualization task), and (iii) knowledge about statistical measures. We mapped these classes into three control variables, and used real‐world time series data to construct stimuli. The results of the study confirmed the positive contribution of each class of knowledge towards the reduction of the potential distortion, while the knowledge about the patterns prevents distortion more effectively than the other two classes.
Visual Comparison of Eye Movement Patterns
Authors: Blascheck Tanja , Schweizer Markus , Beck Fabian , Ertl Thomas 
Published: July 2017

AbstractIn eye tracking research, finding eye movement patterns and similar strategies between participants’ eye movements is important to understand task solving strategies and obstacles. In this application paper, we present a graph comparison method using radial graphs that show Areas of Interest (AOIs) and their transitions. An analyst investigates a single graph based on dwell times, directed transitions, and temporal AOI sequences. Two graphs can be compared directly and temporal changes may be analyzed. A list and matrix approach facilitate the analyst to contrast more than two graphs guided by visually encoded graph similarities. We evaluated our approach in case studies with three eye tracking and visualization experts. They identified temporal transition patterns of eye movements across participants, groups of participants, and outliers.
Visualizing the Uncertainty of Graph‐based 2D Segmentation with Min‐path Stability
Authors: Summa B. , Tierny J. , Pascucci V. 
Published: July 2017

AbstractThis paper presents a novel approach to visualize the uncertainty in graph‐based segmentations of scalar data. Segmentation of 2D scalar data has wide application in a variety of scientific and medical domains. Typically, a segmentation is presented as a single unambiguous boundary although the solution is often uncertain due to noise or blur in the underlying data as well as imprecision in user input. Our approach provides insight into this uncertainty by computing the “min‐path stability”, a scalar measure analyzing the stability of the segmentation given a set of input constraints. Our approach is efficient, easy to compute, and can be generally applied to either graph cuts or live‐wire (even partial) segmentations. In addition to its general applicability, our new approach to graph cuts uncertainty visualization improves on the time complexity of the current state‐of‐the‐art with an additional fast approximate solution. We also introduce a novel query enabled by our approach which provides users with alternate segmentations by efficiently extracting local minima of the segmentation optimization. Finally, we evaluate our approach and demonstrate its utility on data from scientific and medical applications.
Adaptable Radial Axes Plots for Improved Multivariate Data Visualization
Authors: Rubio‐Sánchez M. , Sanchez A. , Lehmann D. J. 
Published: July 2017

AbstractRadial axes plots are multivariate visualization techniques that extend scatterplots in order to represent high‐dimensional data as points on an observable display. Well‐known methods include star coordinates or principal component biplots, which represent data attributes as vectors that define axes, and produce linear dimensionality reduction mappings. In this paper we propose a hybrid approach that bridges the gap between star coordinates and principal component biplots, which we denominate “adaptable radial axes plots”. It is based on solving convex optimization problems where users can: (a) update the axis vectors interactively, as in star coordinates, while producing mappings that enable to estimate attribute values optimally through labeled axes, similarly to principal component biplots; (b) use different norms in order to explore additional nonlinear mappings of the data; and (c) include weights and constraints in the optimization problems for sorting the data along one axis. The result is a flexible technique that complements, extends, and enhances current radial methods for data analysis.
Illustrative Visualization of Mesoscale Ocean Eddies

Published: July 2017

AbstractFeature‐based time‐varying volume visualization is combined with illustrative visualization to tell the story of how mesoscale ocean eddies form in the Gulf Stream and transport heat and nutrients across the ocean basin. The internal structure of these three‐dimensional eddies and the kinematics with which they move are critical to a full understanding of ocean eddies. In this work, we apply a feature‐based method to track instances of ocean eddies through the time steps of a high‐resolution multi‐decadal regional ocean model and generate a series of eddy paths which reflect the life cycle of individual eddy instances. Based on the computed metadata, several important geometric and physical properties of eddy are computed. Illustrative visualization techniques, including visual effectiveness enhancement, focus+context, and smart visibility, are combined with the extracted volume features to explore eddy characteristics at different levels. An evaluation by domain experts indicates that combining our feature‐based techniques with illustrative visualization techniques provides an insight into the role eddies play in ocean circulation. The domain experts expressed a preference for our methods over existing tools.
Allergic contact dermatitis caused by a new temporary blue–black tattoo dye – sensitization to genipin from jagua (Genipa americanaL.) fruit extract

Published: July 2017

SummaryBackgroundTemporary tattoos made with an extract of the jagua fruit (Genipa americana L.) are becoming increasingly popular. It is claimed that it is ‘dermatologically tested’ and does not contain p‐phenylenediamine. Extracts of jagua and gardenia fruits have been used by indigenous people in South America, as well as in traditional Chinese medicine, for centuries. Genipin is currently used for its cross‐linking effect in the manufacture of polysaccharides, and is being investigated for its anti‐inflammatory and other properties.ObjectivesTo report the presence of the allergenic substance genipin in a self‐administered temporary tattoo dye made from the fruit juice of jagua (Genipa americana L.).Patients and methodsA 39‐year‐old female who repeatedly applied ‘completely natural and 100% safe’ Earth Jagua® tattoo, obtained via the internet, to her left hand developed allergic contact dermatitis within 6 weeks. Analysis of the dye showed the presence of geniposide and genipin.ResultsPatch tests with the dye and with its main components, including genipin, gave strong positive reactions to the latter. There was no sensitization to other ingredients or p‐amino compounds.ConclusionsWe report an extensively evaluated case of allergic contact dermatitis caused by a temporary Earth Jagua® tattoo. The allergen identified is genipin, a substance that is increasingly used for tattoos and as a therapeutic agent in medicine. This could result in an increase in the number of allergic reactions in the future.

Published: July 2017

AbstractA translational need exists to understand and predict vancomycin‐induced kidney toxicity. We describe: (i) a vancomycin high‐performance liquid chromatography (HPLC) method for rat plasma and kidney tissue homogenate; (ii) a rat pharmacokinetic (PK) study to demonstrate utility; and (iii) a catheter retention study to enable future preclinical studies. Rat plasma and pup kidney tissue homogenate were analyzed via HPLC for vancomycin concentrations ranging from 3–75 and 15.1–75.5 μg/mL, respectively, using a Kinetex Biphenyl column and gradient elution of water with 0.1% formic acid: acetonitrile (70:30 v/v). Sprague‐Dawley rats (n = 10) receiving 150 mg/kg of vancomycin intraperitoneally had plasma sampled for PK. Finally, a catheter retention study was performed on polyurethane catheters to assess adsorption. Precision was <6.1% for all intra‐assay and interassay HPLC measurements, with >96.3% analyte recovery. A two‐compartment model fit the data well, facilitating PK exposure estimates. Finally, vancomycin was heterogeneously retained by polyurethane catheters.
