Multicriteria approach to select the most economically advantageous tender
Authors: Marcarelli Gabriella , Nappi Andrea 
Published: August 2019

Purpose
This paper aims to show how the proposed approach (two analytic hierarchy process [AHP] models) may allow dealing with the best tender selection process in an organic and simple way and ensure the consistency check of the judgements, the necessary step for having reliable results. At first, this paper highlights some critical issues regarding the weighted sum model (WSM) and the algorithms frequently used to evaluate the most economic advantageous tender. Then, it proposes to extend the AHP approach to the evaluation of both the qualitative and quantitative components of a public procurement award. Finally, the WSM and the AHP are applied to the same case study to show, step by step, some criticisms of the former and some advantages of the latter.

Design/methodology/approach
This paper proposes to apply two AHP models to evaluate both qualitative and quantitative components of a public tender. The quality and cost models allow to identify and select the tender associated with the highest quality/cost ratio.

Findings
The assessment of the WSM and the AHP models, and some differences between them, build upon their application as an example of public procurement. A case study is used as a teaching device (Yin, 2003) to highlight why the AHP may provide different results. In particular, an important issue concerning the evaluation of qualitative requirements is explored: the consistency of judgements expressed by the committee members.

Social implications
This approach provides analytical tools for public management that allow appropriate implementation of their management function and allow a realisation of the strategic objectives of European Union law and Italian legislation on public procurement. It would help managers to prioritise their goals and criteria and evaluate them in a scientific way. The model integrates multiple qualitative and quantitative criteria, simplifies the selection process, achieves optimal use of funds and leads to cost savings. It allows to reduce the discretional power of both the contracting issuer, in the choice of the formula to adopt for calculating the coefficients, and the committee members, allowing tender evaluation to have more trust and ensure the fairness of public procurement matters and quality of the object purchased.

Originality/value
This paper proposes the use of two hierarchical models to evaluate qualitative and quantitative requirements and provide the ranking among several tenders.
Basic research public procurement: the impact on supplier companies
Authors: Dal Molin Martina , Previtali Ezio 
Published: August 2019

Purpose
The purpose of this paper is to estimate and assess the impact of public procurement activities of an Italian basic research center (the National Institute for Nuclear Physics [INFN]) on supplier companies.

Design/methodology/approach
Starting from the exploratory nature of this research, a single case study research strategy has been applied. The impact of basic research public procurement has been estimated using survey data on 168 INFN supplier companies. Supplier companies have been surveyed on six different categories of company outcomes, namely, sales volume, learning and innovation, relationship with the market, alliances and network and social impact.

Findings
Results of the analysis reported that the activity of INFN public procurement generates a positive impact on supplier companies on different dimensions, especially related to learning and innovative outcome and economic impact and market penetration outcome.

Social implications
Policy implications can be derived from the current study. In particular, to support the policymakers in the effort of assessing the impact of basic research public procurement, this study, first highlights the impact dimensions on supplier companies, and second, it provides empirical evidence of public procurement as a viable tool to foster companies’ innovation.

Originality/value
This research explores a relevant but understudied topic that has recently attracted the attention of policymakers. In fact, although public procurement have been recognized as a tool to foster companies’ innovation, empirical evidence is still scant, particularly in the case of basic research.
Adaption of active boundary conditions in structural fire testing
Authors: Qureshi Ramla Karim , Elhami-Khorasani Negar , Gernay Thomas 
Published: August 2019

Purpose
This paper aims to investigate the need for active boundary conditions during fire testing of structural elements, review existing studies on hybrid fire testing (HFT), a technique that would ensure updating of boundary conditions during a fire test, and propose a compensation scheme to mitigate instabilities in the hybrid testing procedure.

Design/methodology/approach
The paper focuses on structural steel columns and starts with a detailed literature review of steel column fire tests in the past few decades with varying axial and rotational end restraints. The review is followed with new results from comparative numerical analyses of structural steel columns with various end constraints. HFT is then discussed as a potential solution to be adapted for fire testing of structural elements. Challenges in contemporary HFT procedures are discussed, and application of stiffness updating approaches is demonstrated.

Findings
The reviewed studies indicate that axial and rotational restraints at the boundaries considerably influence the fire response of steel columns. Equivalent static spring technique for simulating effect of surrounding frame on an isolated column behavior does not depict accurate buckling and post-buckling response. Additionally, numerical models that simulate fire performance of a column situated in a full-frame do follow the trends observed in actual test results up until failure occurs, but these simulations do not necessarily capture post-failure performance accurately. HFT can be used to capture proper boundary conditions during testing of isolated elements, as well as correct failure modes. However, existing studies showed cases with instabilities during HFT. This paper demonstrates that a different stiffness updates calculated from the force-displacement response history of test specimen at elevated temperature can be used to resolve stability issues.

Originality/value
The paper has two contributions: it suggests that the provision of active boundary conditions is needed in structural fire testing, as equivalent static spring does not necessarily capture the effect of surrounding frame on an isolated element during a fire test, and it shows that force-displacement response history of test specimen during HFT can be used in the form of a stiffness update to ensure test stability.
Assessing undergraduate information literacy change over time
Authors: Ault Arthur Brian , Ferguson Jessame 
Published: August 2019

Purpose
The research project assessed information literacy skill changes in college students at two points in time, as entering first-year students in 2012 and as seniors in their senior seminar capstone courses in the 2015–2016 academic year. The paper aims to discuss this issue.

Design/methodology/approach
The Standardized Assessment of Information Literacy Skills (SAILS) individual test was the selected instrument. Version 1 of the test was used for first-year students and Version 2 was used for seniors. All testing was done in person in computer labs with a librarian or library staff member present to proctor the test. This resulted in obtaining 330 student results as first years and 307 as seniors, with 161 exact matches for both administrations of the test. Exact matching of student scores to demographic details pulled from the college’s student information systems were used in the analysis.

Findings
The analysis shows that overall first-year students tested below the 70 percent proficiency benchmark in all eight skill sets, but by the time they were seniors they scored above 70 percent in three skill sets. Male students and students of color performed lower than their counterparts, but these groups did demonstrate significant improvement in four skill sets by the time they were seniors. Students in the Honors program, those who took longer to complete the test as seniors, those with higher GPAs, those in Humanities majors, and those who had upper level course exposures to librarian information literacy instruction had higher performance on the test. There were no statistically significant results for students who were first generation, Pell Grant eligible, or were in-state or out-of-state residents.

Originality/value
There are few published studies that utilized the SAILS test for longitudinal institution-wide assessment. The majority of institutions that utilized the individual version of SAILS did so to determine change within a selected course, or set of courses, in the same semester and very few are published.
Multi-objective optimization approach in design for additive manufacturing for fused deposition modeling
Authors: Asadollahi-Yazdi Elnaz , Gardan Julien , Lafon Pascal 
Published: August 2019

Purpose
This paper aims to provide a multi-objective optimization problem in design for manufacturing (DFM) approach for fused deposition modeling (FDM). This method considers the manufacturing criteria and constraints during the design by selecting the best manufacturing parameters to guide the designer and manufacturer in fabrication with FDM.

Design/methodology/approach
Topological optimization and bi-objective optimization problems are suggested to complete the DFM approach for design for additive manufacturing (DFAM) to define a product. Topological optimization allows the shape improvement of the product through a material distribution for weight gain based on the desired mechanical behavior. The bi-objective optimization problem plays an important role to evaluate the manufacturability by quantification and optimization of the manufacturing criteria and constraint simultaneously. Actually, it optimizes the production time, required material regarding surface quality and mechanical properties of the product because of two significant parameters as layer thickness and part orientation.

Findings
A comprehensive analysis of the existing DFAM approaches illustrates that these approaches are not developed sufficiently in terms of manufacturability evaluation in quantification and optimization levels. There is no approach that investigates the AM criteria and constraints simultaneously. It is necessary to provide a decision-making tool for the designers and manufacturers to lead to better design and manufacturing regarding the different AM characteristics.

Practical implications
To assess the efficiency of this approach, a wheel spindle is considered as a case study which shows how this method is capable to find the best design and manufacturing solutions.

Originality/value
A multi-criteria decision-making approach as the main contribution is developed to analyze FDM technology and its attributes, criteria and drawbacks. It completes the DFAM approach for FDM through a bi-objective optimization problem which deals with finding the best manufacturing parameters by optimizing production time and material mass because of the product mechanical properties and surface roughness.
Simultaneous positron emission tomography and magnetic resonance imaging for the detection and characterisation of liver lesions in patients with colorectal cancer: A pictorial review
Authors: Yeoh Edward , Miles Ken 
Published: August 2019

SummaryPatients with colorectal cancer undergo frequent diagnostic imaging to stage the extent of metastatic disease and assess response to treatment. Imaging is typically via diagnostic contrast‐enhanced CT or combined FDG‐PET/CT. However, recent research has demonstrated promising benefits of combined FDG‐PET/MRI in oncologic imaging due to the superior soft‐tissue contrast of MRI. The extent of both intrahepatic and extrahepatic disease is important in establishing treatment options for colorectal cancer patients, and FDG‐PET/CT and dedicated liver imaging are often both required. FDG‐PET/MRI offers the advantage of a single examination which can be completed within a similar duration as dedicated liver MRI imaging. This improves patient convenience and anatomical co‐registration between PET and MRI imaging and provides a potential cost benefit. The diagnostic benefits of FDG‐PET/MRI include the simultaneous characterisation of focal liver lesions, exclusion of extrahepatic disease, the detection of additional hepatic metastases and extrahepatic disease, and the multi‐parametric assessment of treatment response. This pictorial review highlights examples of these benefits.
High‐dose ethanol intoxication decreases 1/f neural noise or scale‐free neural activity in the resting state
Authors: Stock Ann‐Kathrin , Pertermann Maik , Mückschel Moritz , Beste Christian 
Published: August 2019

AbstractBinge drinking is a frequent phenomenon in many western societies and has been associated with an increased risk of developing alcohol use disorder later in life. Yet, the effects of high‐dose alcohol intoxication on neurophysiological processes are still quite poorly understood. This is particularly the case given that neurophysiological brain activity not only contains recurring (oscillatory) patterns of activity, but also a significant fraction of “scale‐free” or arrhythmic dynamics referred to as 1/f type activity, pink noise, or 1/f neural noise. Neurobiological considerations suggest that it should be modulated by alcohol intoxication. To investigate this assumption, we collected resting state EEG data from n = 23 healthy young male subjects in a crossover design, where each subject was once tested sober and once tested while intoxicated (mean breath alcohol concentration of 1.1 permille ±0.2). Analyses of the 1/f neural dynamics showed that ethanol intoxication decreased resting state 1/f neural noise, as compared with a sober state. The effects were strongest when the eyes were closed and particularly reliable in the beta frequency band. Given that the dynamics of the beta band have been shown to strongly depend on GABAA receptor neural transmission, this finding nicely aligns with the fact that ethanol increases GABAergic signaling. The study reveals a currently unreported effect of binge drinking on neurophysiological dynamics, which likely revealed a higher sensitivity for ethanol effects than most commonly considered measures of power in neural oscillations. Implications and applicability of these findings are discussed.
Fungal pathogen and ethanol affect host selection and colonization success in ambrosia beetles
Authors: Rassati Davide , Contarini Mario , Ranger Christopher M. , Cavaletto Giacomo , Rossini Luca , Speranza Stefano , Faccoli Massimo , Marini Lorenzo 
Published: August 2019

AbstractAmbrosia beetles exhibit broad host ranges but a narrow preference based on the condition of the host. Tissues infected by pathogens or containing ethanol can facilitate attacks by ambrosia beetles, although it still remains unclear how these factors interact.The present study aimed to examine how (i) chestnut logs infected with the fungal pathogenCryphonectria parasiticaand treated with ethanol (i.e. baited with ethanol lure, soaked in ethanol or untreated) and (ii) hornbeam logs soaked in different ethanol concentrations (3–12.5%) affect host selection and colonization success of ambrosia beetles.Ethanol‐soaked logs were more attractive toAnisandrus disparthan ethanol‐baited logs or untreated logs, although this difference was more evident in uninfected than infected logs. Increasing ethanol concentration in host tissues was differentially attractive toXyleborinus saxeseniiandXylosandrus germanus. A nonlinear relationship was also documented between ethanol concentration and emergence ofX. germanusadults.Overall, the results obtained suggest that the presence ofC. parasiticain chestnut logs can affect host selection in ambrosia beetles. In addition, the ethanol concentration in tree tissues affects host selection and colonization success, although the effect varies depending on the beetle species. This contrasting response could be a niche‐partitioning mechanism based on ethanol within host tissues.
U.S. sweeteners: Combating excess consumption with an excise tax?
Authors: Lakkakula Prithviraj , Schmitz Andrew 
Published: August 2019

AbstractObesity is a public health problem in the United States that has been linked to excess sweetener consumption. The American Heart Association (AHA) recommends no more than 6–9 teaspoons/capita/day, while the U.S. Food and Drug Administration (FDA) recommends 200 calories/capita/day of caloric sweetener consumption. Both recommendations are well below the reported 2016 sweetener consumption levels. We quantify the input tax rates needed to reduce the current excess sweetener consumption level to the AHA and FDA recommended standards. We calculate the joint tax in the United States on two major sweeteners, sugar and High Fructose Corn Syrup (HFCS), to be 31 and 24 cents per pound, respectively, based on the AHA standard, and 19 and 17 cents per pound, respectively, using the FDA standard. These taxes would be roughly the magnitude of the existing sugar and HFCS prices. In both cases, the tax incidence on producers is much smaller than on consumers. Our focus is very different from past studies in that it deals with the effect of taxes on inputs to meet the recommended target rather than a selective tax (sugar‐sweetened beverage tax). If a sweetener tax were implemented, U.S. sugar and HFCS producers would lose US$398–US$489 and US$683–US$844 million per year, respectively.
Differences in the Selvester QRS score after primary PCI strategy and conservative treatment for STEMI patients with negative T waves

Published: August 2019

AbstractBackgroundAccording to current guidelines, the main indications for PCI in patients with STEMI are ST‐segment deviations and defined time from the onset of symptoms. Negative T wave at admission can be a sign of prolonged ischemia or spontaneous reperfusion. In both situations, the urgent intervention is questionable. We evaluated the infarct size and in‐hospital mortality in STEMI patients with negative T wave in cases of primary PCI strategy compared with conservative treatment.MethodsA retrospective analysis of 116 STEMI patients with negative T wave at the presenting ECG was performed. Sixty‐eight patients (59%) underwent primary PCI strategy (PCI group), and 48 (41%) were treated conservatively (non‐PCI group). The infarct size estimated by using the Selvester score, and in‐hospital mortality were evaluated.ResultsThe difference between Selvester score values at admission and at discharge in the non‐PCI group was statistically significant (1.48; 95% CI 0.694–2.27), while no significant difference was observed in the PCI group (−0.07; 95% CI −0.546–0.686). The in‐hospital mortality was higher in the non‐PCI group; however, the numbers were relatively small: PCI 2 (2.9%) and non‐PCI 5 (10.4%).ConclusionIn this study, we showed a reduction in the infarct size estimated by Selvester score in STEMI patients with negative T wave who were treated conservatively, while there was no significant change in the infarct size after primary PCI strategy. The higher mortality in patients treated conservatively could be attributed to higher age and comorbidities in the non‐PCI group. It seems that conservative treatment strategy might be an option in STEMI patients with negative T wave.
Victories from Insurgency: Re‐Negotiating Housing, Community Control, and Citizenship at the Margins
Authors: Cahen Claire , Schneider Jakob , Saegert Susan 
Published: August 2019

AbstractThis article considers how insurgent campaigns for housing the poor in New York City and Chicago succeeded in engaging the local state, non‐profits and financial institutions in the creation of community land trusts. These campaigns had long arcs in which victories and losses built from each other, neither as permanent as they initially seemed. The campaigns moved iteratively between spaces of “invited citizenship” (courtrooms, planning committees) and “invented” spaces of collective action (property takeovers). They found their greatest success when, exploiting state incapacity to defend abandoned property, they elicited a degree of complicity from local governments in their takeovers of housing and land. The article thus contests dichotomised accounts of social movements that oppose losses to victories, cooptation to resistance, and movements to institutions. Instead, we call for situated and dynamic accounts of insurgent practice, capable of theorising the long, messy, co‐constituted evolution of political contexts and popular struggle.
