AGUTER a platform for automated generation of user acceptance tests from requirements specifications
Authors: Antonelli Leandro , Camilleri Guy , Torres Diego , Zarate Pascale 
Published: September 2021

PurposeThis article proposes a strategy to make the testing step easier, generating user acceptance tests (UATs) in an automatic way from requirements artifacts.Design/methodology/approachThis strategy is based on two modeling frameworks: scenarios and task/method paradigm. Scenarios are a requirement artifact used to describe business processes and requirements, and task/method paradigm is a modeling paradigm coming from the artificial intelligence field. The proposed strategy is composed of four steps. In the first step, scenarios are described through a semantic wiki website. Then scenarios are automatically translated into a task/method model (step two). In the third step, the task/method model obtained in step two is executed in order to produce and store all possible achievements of tasks and thus scenarios. The stored achievements are saved in a data structure called execution tree (ET). Finally, from this ET (step four), the UATs are generated.FindingsThe feasibility of this strategy is shown through a case study coming from the agriculture production systems field.Originality/valueGenerally, test design approaches deal with a small number of variables describing one specific situation where a decision table or workflow is used to design tests. The proposed approach can deal with many variables because the authors rely on scenarios that can be composed in order to obtain a tree with all the testing paths that can arise from their description.

Does sustainability reporting promote university ranking? Australian and New Zealand evidence
Authors: Shan Yuan George , Zhang Junru , Alam Manzurul , Hancock Phil 
Published: September 2021

Purpose
This study aims to investigate the relationship between university rankings and sustainability reporting among Australia and New Zealand universities. Even though sustainability reporting is an established area of investigation, prior research has paid inadequate attention to the nexus of university ranking and sustainability reporting.

Design/methodology/approach
This study covers 46 Australian and New Zealand universities and uses a data set, which includes sustainability reports and disclosures from four reporting channels including university websites, and university archives, between 2005 and 2018. Ordinary least squares regression was used with Pearson and Spearman’s rank correlations to investigate the likelihood of multi-collinearity and the paper also calculated the variance inflation factor values. Finally, this study uses the generalized method of moments approach to test for endogeneity.

Findings
The findings suggest that sustainability reporting is significantly and positively associated with university ranking and confirm that the four reporting channels play a vital role when communicating with university stakeholders. Further, this paper documents that sustainability reporting through websites, in addition to the annual report and a separate environment report have a positive impact on the university ranking systems.

Originality/value
This paper contributes to extant knowledge on the link between university rankings and university sustainability reporting which is considered a vital communication vehicle to meet the expectation of the stakeholder in relevance with the university rankings.
Research on the printing error of tilted vertical beams in delta-robot 3D printers
Authors: Wang Yuezong , Liu Jinghui , Guo Mengfei , Wang LiuQIan 
Published: September 2021

Purpose
A three-dimensional (3D) printing error simulation approach is proposed to analyze the influence of tilted vertical beams on the 3D printing accuracy. The purpose of this study is to analyze the influence of such errors on printing accuracy and printing quality for delta-robot 3D printer.

Design/methodology/approach
First, the kinematic model of a delta-robot 3D printer with an ideal geometric structure is proposed by using vector analysis. Then, the normal kinematic model of a nonideal delta-robot 3D robot with tilted vertical beams is derived based on the above ideal kinematic model. Finally, a 3D printing error simulation approach is proposed to analyze the influence of tilted vertical beams on the 3D printing accuracy.

Findings
The results show that tilted vertical beams can indeed cause 3D printing errors and further influence the 3D printing quality of the final products and that the 3D printing errors of tilted vertical beams are related to the rotation angles of the tilted vertical beams. The larger the rotation angles of the tilted vertical beams are, the greater the geometric deformations of the printed structures.

Originality/value
Three vertical beams and six horizontal beams constitute the supporting parts of the frame of a delta-robot 3D printer. In this paper, the orientations of tilted vertical beams are shown to have a significant influence on 3D printing accuracy. However, the effect of tilted vertical beams on 3D printing accuracy is difficult to capture by instruments. To reveal the 3D printing error mechanisms under the condition of tilted vertical beams, the error generation mechanism and the quantitative influence of tilted vertical beams on 3D printing accuracy are studied by simulating the parallel motion mechanism of a delta-robot 3D printer with tilted vertical beams.

Published: September 2021

Purpose
The purpose of this study is to validate a novel model of resting hand splint manufactured by additive manufacturing (AM) and compare it with the traditional model manufactured by high temperature thermoplastic in terms of cost, weight, volume and thermal comfort.

Design/methodology/approach
A novel resting hand splint model was created from the topology optimization (TO) and analyzed, by finite-element analysis, manufacturing cost and weight, with a traditional resting hand splint. A pilot clinical study was carried out to verify heat diffusion during the use of the two splints.

Findings
The results showed that compared with the traditional model, the novel model reduced the volume of material used by 35.48%, the weight of the orthosis by 17.56% and the maximum surface deformation by 171.17% when subjected to actuation forces. It was also verified that, when manufactured with Nylon by AM, the new model is 1.5 times cheaper than the traditional model made of Polypropylene. The result of the thermographic analysis showed greater temperature variation in the use of the traditional splint (+4.6°C) compared to the temperature variation observed in the nylon splint (2.1°C).

Practical implications
These results have as clinical relevance the demonstration of the feasibility of manufacturing functional orthoses that are more comfortable, cheaper and lighter than traditional ones.

Originality/value
This study describes the use of TO to manufacture a novel resting hand splint, which was compared with the commonly used traditional splint in terms of mechanical resistance, weight, cost and thermal comfort.
Inference of local invasion pathways in two invasive crayfish species displaying contrasting genetic patterns
Authors: Paz‐Vinas Ivan , Lang Iris , Millet Paul , Veyssière Charlotte , Loot Géraldine , Cucherousset Julien 
Published: September 2021

Abstract

The efficient management of invasive alien species (IAS) requires the identification of their introduction pathways. Genetic assessments have proven useful to inform invasion pathways at large (national to worldwide) scales, but studies at local scales are still rare, despite their importance for guiding management.

In this study, genetic analyses were used to identify local invasion pathways of two invasive crayfish species (the spiny‐cheek crayfish Faxonius limosus and the red swamp crayfish Procambarus clarkii) in a dense network of artificial lakes. We first characterized the spatial patterns of genetic variability, effective population sizes (Ne) and among‐lakes recent migration events for each species using neutral microsatellite markers. We then identified the environmental factors affecting genetic variability and inferred the potential local invasion pathways.

Results revealed different patterns of genetic variability between the two species: F. limosus displayed very low levels of genetic diversity, Ne and spatial structuring compared to P. clarkii, which displayed high genetic diversity, Ne and spatial genetic structuring. We also demonstrated context‐dependent effects of different environmental factors (fishery management, spatial distribution and lake size) on genetic variability indices.

We did not identify local invasion pathways for F. limosus due to limited genetic variability, likely caused by a strong founder effect and potential parthenogenetic reproduction. Contrastingly, multiple invasion pathways (release, contaminant, unaided/corridor spread and stowaway) were identified for P. clarkii.

Synthesis and applications. Although limited in some particular cases (e.g. for species having experienced strong shaping events and/or displaying asexual reproductive modes), neutral genetic variation assessments can provide important insights for inferring local invasion pathways in complex landscapes for invasive alien species displaying short generation times and complex invasion histories.
The influence of life‐history strategy on ecosystem sensitivity to resource fluctuations
Authors: Felton Andrew J. , Snyder Robin E. , Shriver Robert K. , Suding Katharine N. , Adler Peter B. 
Published: September 2021

Abstract

To cope with uncertainty and variability in their environment, plants evolve distinct life‐history strategies by allocating different fractions of energy to growth, survival and fecundity. These differences in life‐history strategies could potentially influence ecosystem‐level dynamics, such as the sensitivity of primary production to resource fluctuations. However, linkages between evolutionary and ecosystem dynamics are not well understood.

We used an annual plant population model to ask, when might differences in plant life‐history strategies produce differences in the sensitivity of primary production to resource fluctuations?

Consistent with existing theory, we found that a highly variable and unpredictable environment led to the evolution of a conservative strategy characterized by relatively low and invariant germination fractions, while a variable but predictable environment favoured a riskier strategy featuring more variable germination fractions. Unexpectedly, we found that the influence of life‐history strategy on the sensitivity of production to resource fluctuations depended on competitive interactions, specifically the rate at which production saturates with the number of competing individuals. Rapid saturation overwhelms the influence of life‐history strategy, but when production saturates more slowly, the risky strategy translated to high sensitivity, whereas the conservative strategy translated to low sensitivity.

Empirical estimates from Sonoran Desert annual plant populations indicate that production saturates relatively rapidly with the number of individuals for most species, suggesting that life‐history differences are unlikely to alter sensitivity of production to resource fluctuations, at least in this community.

Synthesis. Our modelling results imply that research to understand the sensitivity of primary production to resource fluctuations should focus more on the intraspecific competitive interactions shaping the density–yield relationship than on the life‐history strategies that determine temporal risk‐spreading.
Fat‐free fermented concentrated milk products as milk protein‐based microgel dispersions: Particle characteristics as key drivers of textural properties
Authors: Heck Anisa J. , Schäfer Johannes , Nöbel Stefan , Hinrichs Jörg 
Published: September 2021

AbstractThe popularity of fat‐free fermented concentrated milk products, such as fresh cheeses and high‐protein yogurt, has increased over the recent years, attributed to greater availability and improvements in taste and texture. These improvements have been achieved through modifications and new developments in processing technologies, for example, higher heat treatment intensities and incorporating different membrane filtration technologies. Though numerous processing parameters are discussed in the literature, as well as reasons behind the developments, detailed examinations of how process modifications affect the final textural attributes of these products are lacking. To draw links between processing parameters and texture, we review the literature on fat‐free fermented concentrated milk products from the perspective of fermented milk protein‐based microgel particles as the basic structural unit. At each main processing step, relationships between process parameters, micro‐ and macrostructural and sensory (textural) properties are discussed.An overview of particle characteristics that drive structural changes at each processing step is developed in relation to textural characteristics. Using this approach of assessing relationships between structural characteristics of concentrated dispersions of fat‐free fermented milk protein‐based microgel particles and processing parameters provides a basic context for the selection of optimal parameters to achieve a desired texture.

Published: September 2021

AbstractInfectious diseases are an important cause of mortality in patients with renal failure. The markers used to diagnose infection in patients with renal failure have various limitations. Culture positivity is an objective guide in that context. The purpose of this study was to examine the effectiveness of frequently used markers of bacterial infection in predicting culture positivity in renal failure patients with renal failure hospitalized with suspected bacterial infection over an approximately 1.5‐year period were included in this prospective observational study. Patients' demographic and laboratory findings were recorded. Demographic and laboratory findings and mortality were compared between patients with and without culture‐positivity. Parameters affecting culture positivity were also analyzed. Four hundred twenty‐six patients (median age 67.50, 45.5% female) were included in the study. Culture positivity was determined in 54.5% of patients. Hospital stay was longer (p < 0.001) and leukocyte (p < 0.001), neutrophil percentage (p < 0.05) and CRP (p < 0.001) values were significantly higher in culture‐positive patients. Mortality was also significantly higher in culture‐positive patients than in culture‐negative patients (p < 0.05). CRP was determined as a predictor of culture positivity at logistic regression analysis (p = 0.000, exp ß [1.004]). Culture positivity was determined in more than half of the patients hospitalized with suspected bacterial infection. CRP, a longstanding marker, was identified as a parameter predicting culture positivity. We think that the determination in further studies of a cut‐off point for CRP in determining culture positivity may be a useful diagnostic guide.

Published: September 2021

AbstractPolycaprolactone (PCL)was used via double emulsion/solvent evaporation technique for the encapsulation of polyphenols olive leaves (OLs) extracts. In this study, the PCL‐microcapsules loaded with OLs polyphenols extract powder were characterized by scanning electron microscopy and fourier transform infrared spectrometry analysis. Their total phenolic (TPC), total flavonoid (TFC) contents, and antioxidant activities (DPPH, FRAP, and ABTS), and polyphenols stability were measured after oral, gastric, and intestinal steps of in vitro digestion. PCL‐microcapsules were utilized in formulating novel functional yogurt containing 0, 25, 50, and 75 mg of TPC estimated as mg GAE (added as PCL‐microcapsules) per 100g yogurt. All yogurt samples were evaluated for their pH, acidity, syneresis, viscosity, and color during storage. In vitro digestion significantly affected the phenolic composition in non‐encapsulated extract whereas it had a lower impact on encapsulated phenolics. Higher protection was provided for encapsulated OLs extract and their higher release was observed at the intestinal phase. Unlike the undigested OLs extract, which had a TPC of 490 mg GAE/100 g, lower values of TPC (136 and 289 mg GAE/100 g) were obtained for non‐encapsulated and encapsulated OLs extract, respectively, in the intestinal fluids. Yogurt with PCL‐microcapsules had lower viscosity, syneresis, and color parameters, compared to control yogurt. Thus, OLs represent a valuable and cheap source of polyphenols that can be successfully applied in microencapsulated form, in formulating functional yogurt.

Published: September 2021

AbstractChinese people have consistentlypreferred high mountain tea because specific flavors are memorable for them, and also, people have traditionally considered this type of tea to be good for health. Tieguanyin is one of the famous traditional Chinese tea that has ever‐changing aromas. To illustrate the various characteristics in volatile fragment compounds from Tieguanyin tea, fresh tea leaves collected from different elevations (450, 650, and 900 m) were detected using GC‐MS by solid–liquid extraction. The results showed that volatile aromatic compounds, such as benzyl alcohol, phenyl ethanol, and acetophenone, were the most abundant in tea leaves located with high elevation. Meanwhile, 1‐hexanol, 1‐nananol, and nanoic acid, as a type of aliphatic aroma, were more prevalent in low‐elevation tea orchards. Catechols and alkaloids are largely cumulated in low‐ and high‐elevation tea leaves, respectively. Our findings also showed that elemene was widely consisted of high‐elevation tea metabolites. It provided practicality for the preparation of tea manufacturing in major Tieguanyin tea‐producing regions.
