Mock-ups as a tool for assessing customer value early in the development process
Authors: Lyly-Yrjänäinen Jouni , Aarikka-Stenroos Leena , Laine Teemu 
Published: February 2019

Purpose
This paper aims to propose an approach to broaden the focus of a low-fidelity prototype (i.e. mock-up) to enable user experimentation in a real environment at the early stages of the product development process. The functionality approaching a real solution enables customers to experience the key functionality, and therefore, the perceived customer value of the new product idea before major investments in the development.

Design/methodology/approach
The study is based on an interventionist case study in a manufacturing company. The researchers were involved in the development of two new products and analysing the potential process and cost implications.

Findings
Mock-ups enable the preliminary measurement of cost and value implications of a new product at the early stages of the development process. This holds significant potential for advancing development practices and reducing the uncertainties present in such processes. Thus, the business case at the early stage of the development process can be argued with “user-experienced” cost information and, therefore, also “perceived” customer value.

Practical implications
The use of mock-ups to gain customer feedback is well aligned with the fail-fast mentality emphasised in the contemporary start-up scene, but this study also encourages developers/practitioners from mature industries to use mock-ups to assess perceived customer value.

Originality/value
The originality of the paper lies in broadening the focus of mock-ups to enable user experimentation in a real environment at the early stages of the development process.

Authors: Zimand Sheiner Dorit , Earon Amir 
Published: February 2019

PurposeThe purpose of this paper is to focus on transformations in the advertising industry from the point of view of the role and position of account planners. It questions the current viability of account planning (AP) as a result of digital disruptions.Design/methodology/approachIn total, 18 face-to-face responsive interviews were conducted among professionals who hold planning responsibilities at advertising agencies. A theoretical thematic analysis revealed five main themes which are associated with the disruption of AP roles.FindingsThe research points out that AP is a profession in transition as part of the advertising industry that is undergoing a major shift. Digital transformations have not yet crystallized in the business domain, and so this period is one of learning and adjustment.Research limitations/implicationsIt is suggested for advertising practitioners, as well as marketing executives, to encourage AP departments to re-think the core significance of the AP department since the AP role needs to be repositioned or even redefined.Originality/valueThe current research has several significant implications for theory and practice: confronting the role of the strategist in advertising agencies vs digital strategy and Big Data; contributing to the understanding of the dynamics of AP transitional roles as a starting point for re-examination of the advertising creative process; and calling for more research exploring the relationship between agency adoption of digital tools and its approach to AP.

Published: February 2019

Purpose
There is significant national interest in tackling issues surrounding the needs of vulnerable children and adults. This paper aims to argue that much value can be gained from the application of new data-analytic approaches to assist with the care provided to vulnerable children. This paper highlights the ethical and information governance issues raised in the development of a research project that sought to access and analyse children’s social care data.

Design/methodology/approach
The paper documents the process involved in identifying, accessing and using data held in Birmingham City Council’s social care system for collaborative research with a partner organisation. This includes identifying the data, its structure and format; understanding the Data Protection Act 1998 and 2018 (DPA) exemptions that are relevant to ensure that legal obligations are met; data security and access management; the ethical and governance approval process.

Findings
The findings will include approaches to understanding the data, its structure and accessibility tasks involved in addressing ethical and legal obligations and requirements of the ethical and governance processes.

Originality/value
The aim of this research is to highlight the potential use of use new data-analytic techniques to examine the flow of children’s social care data from referral, through the assessment process, to the resulting service provision. Data held by Birmingham City Council are used throughout, and this paper highlights key ethical and information governance issues which were addressed in preparing and conducting the research. The findings provide insight for other data-led studies of a similar nature.
3D Seismic survey design using mixed‐radix based algorithm inversion
Authors: Santos Atahebson B. , Porsani Milton J. , Góis Manuelle S. 
Published: February 2019

ABSTRACTThe determination of three‐dimensional geometry and acquisition parameters, the seismic acquisition survey design, is constantly subject of studies in obtaining data with the highest seismic quality, operational efficiency and cost minimization. In this paper, we propose a methodology for inverting geometry parameters of three‐dimensional orthogonal land seismic surveys based on a direct search method using a mixed‐radix based algorithm. In this algorithm, the search space is discretized on a mixed‐radix base, which depends on the extreme values and the search resolution of each parameter. We will show how to reparametrize the orthogonal acquisition geometry elements in order to obtain the independents and integers parameters that are necessary to construct the mixed‐radix base. For the optimization purpose, we define an objective function to contemplate target parameters associated with the elements of the acquisition geometry directly related to the geophysical and operational constraints. Taking in account that the mathematical functions and the objective function we define for the problem have no significant computational cost, all model space parameters are fast and efficiently tested. We applied the algorithm, using as input data, provided by a one‐line roll orthogonal reference geometry, assuming a pair of geological objectives as shallow and deep targets. All selected models that meet both the proposed objectives and the constraints are organized by decreasing order of fitness so that with the mixed‐radix inversion algorithm we found not only the best model, but also a set of suitable models. Likewise, with the best set of geometries, it is possible to establish a direct comparison between them, analysing their adherence to the technical and operational requirements according to the availability and degree of detail of each one. We show the top 10 best results as a table, allowing a direct comparison between all aspects of these geometries, and we summarize the results showing graphically the fitness of all selected geometries and the inverted geometry elements for the 1000 best geometries. These graphical displays provide a direct way to understand how each model behaves as the fitness decreases. The algorithm is very flexible and its application can be extended to any environment and type of acquisition geometry, and in any phase study of an area be it regional, exploratory or development.

Published: February 2019

SummaryMangroves are forest ecosystems located at the interface between land and sea where sediments presented a variety of contrasted environmental conditions (i.e. oxic/anoxic, non‐sulfidic/sulfidic, organic matter content) providing an ideal ecosystem to study microbial communities with niche differentiation and distinct community structures. In this work, prokaryotic and fungal compositions were investigated during both wet and dry seasons in New Caledonian mangrove sediments, from the surface to deeper horizons under the two most common tree species in this region (Avicennia marina and Rhizophora stylosa), using high‐throughput sequencing. Our results showed that Bacteria and Archaea communities were mainly shaped by sediment depth while the fungal community was almost evenly distributed according to sediment depth, vegetation cover and season. A detailed analysis of prokaryotic and fungal phyla showed a dominance of Ascomycota over Basidiomycota whatever the compartment, while there was a clear shift in prokaryotic composition. Some prokaryotic phyla were enriched in surface layers such as Proteobacteria, Euryarchaeota while others were mostly associated with deeper layers as Chloroflexi, Bathyarchaeota, Aminicenantes. Our results highlight the importance of considering fungal and prokaryotic counterparts for a better understanding of the microbial succession involved in plant organic matter decomposition in tropical coastal sediments.
Fiduciary Duty under the Microscope: Stewardship and the Spectrum of Pension Fund Engagement
Authors: Tilba Anna , Reisberg Arad 
Published: February 2019

AbstractUK pension fund trustees’ interpretations of their fiduciary duties may shape pension fund approaches to corporate stewardship and engagement envisioned by the UK Stewardship Code. Data from interviews with pension fund trustees, executives, investment intermediaries and pensions experts reveals interpretive pluralism of the concept of fiduciary duty in the area of pension funds. This article develops a model identifying the spectrum of pension fund engagement, linking interpretations of fiduciary duty to intensity and methods of engagement in practice. The findings help disambiguate the concept of ‘Fiduciary Duty’, highlighting the practical challenges of Stewardship Code application. These insights are relevant to the ongoing revisions of the Stewardship Code and policy clarifications of the nature of fiduciary duty by the UK Financial Conduct Authority. The paper encourages trustees, regulators and others to consider what role pension fund trustees should have in stewardship, which may not be directly relevant to their fiduciary duties as trustees.
Evaluation of a simple risk score to predict preterm pre‐eclampsia using maternal characteristics: a prospective cohort study
Authors: Sovio U , Smith GCS 
Published: February 2019

Objectives(1) To derive a simple risk score for preterm pre‐eclampsia based on the model used in the ASPRE trial, and (2) to compare it (i) with the original ASPRE algorithm, (ii) with the NICE Guideline score, and (iii) with and without biochemical and ultrasonic predictors.DesignProspective cohort study.SettingCambridge, UK.Population or Sample4184 nulliparous women from the Pregnancy Outcome Prediction study.MethodsMaternal history model coefficients from the ASPRE algorithm were translated into a risk score, preserving the relative weight of each coefficient.Main outcome measuresPreterm delivery with a diagnosis of pre‐eclampsia.ResultsThe area under the ROC curve (AUC) for preterm pre‐eclampsia was 0.846 (95% CI 0.787–0.906) for the risk score and 0.854 (95% CI 0.795–0.914) for the original ASPRE algorithm (P = 0.14). In all, 9.1% of women had a risk score of ≥30 and their risk ratio for preterm pre‐eclampsia was 13.3 (95% CI 6.3–27.8), sensitivity 57.1% (37.5–74.8%), false‐positive rate (1‐specificity) 8.8% (8.0–9.7%), and LR+ 6.5 (4.6–9.1). The score had higher specificity than the NICE Guideline criteria. First trimester levels of PAPP‐A and PlGF were not predictive when included in a model with the risk score. In contrast, mean arterial pressure at booking and 20‐week uterine artery Doppler were independently associated with preterm pre‐eclampsia and the latter modestly increased the AUC (by ~0.02).ConclusionsA simple risk score derived from the ASPRE screening study predictive model provided clinically useful prediction of the risk of preterm pre‐eclampsia.Tweetable abstractA simple risk score derived from the ASPRE screening study provided clinically useful prediction of the risk of preterm pre‐eclampsia.
Marine Mollusks: Food with Benefits
Authors: Khan Bilal Muhammad , Liu Yang 
Published: February 2019

AbstractThe extremely vast biodiversity represented by marine mollusks alongside their widespread utility as a source of food and their high nutritional value has aroused great interest from the scientific community. Furthermore, they can be caught with ease, and their commercial breeding and farming is rampant. This article comprehends the global availability of these organisms, their pretreatment and handling procedures, and their health‐promoting potential with a focus on their antiviral, anti‐inflammatory, and antimicrobial properties. The emphasis herein is on their potential use in the food and nutraceutical industry. In addition, mollusks consumption as part of everyday diet can also be helpful in avoiding many ailments as they are rich in vital nutrients and active secondary metabolites, as well as have the ability to enhance immune response. Moreover, the available literature suggests that normal cooking practices have no notable adverse effects on their nutritional value and they retain certain bioactivities even after the action of digestive enzymes. Though mollusks have been widely studied in relation to the health‐promoting effects reviewed here, there is still more scope for further research in this direction in order to fully utilize this enormous source of food and nutraceuticals.

Published: February 2019

AbstractPolice witness intelligence stated a murdered adult male “Fred” had been vertically buried in wooded hilly terrain 30 years ago in the Midlands, U.K. Conventional search methods were unsuccessful; therefore, the police requested a geophysical investigation to be undertaken to determine whether “Fred” could be detected. A multiphased geophysical approach was conducted, using bulk ground conductivity and metal detectors, then follow‐up magnetics and ground penetrating radar (GPR) survey profiles on electromagnetic (EM) anomalous areas. A tight grid pattern was used to account for the reduced target size. Relatively high‐resolution EM and GPR techniques were determined optimal for this terrain and sandy soil. Geophysical anomalies were identified and the most promising intrusively investigated, and this was found to be a large boulder and tree roots. Study implications suggest careful multiphase geophysical surveys are best practice and give confidence in cold case searches. This study yielded a no‐body result, effectively saving police time and costs from further investigations.

AbstractObjectiveThe present study explores factors related to length of stay (LOS) in a rural public hospital in Thailand and assesses the feasibility of using LOS as an ED key performance indicator.MethodsUsing a mixed‐methods approach, qualitative methods (in‐depth interviews, patients’ chart review and participatory observations) were used to guide and elaborate findings from quantitative analysis of 555 electronic ED records.ResultsMultivariate analysis revealed that age, Emergency Severity Index score and number of laboratory tests were significantly associated with LOS. The qualitative approach provided contradicting evidence on the linkage between LOS and patient outcomes. On the one hand, considering the 4 h rule, a child with asthma was referred to a tertiary care hospital because of deterioration after 4 h of ED care. On the other hand, a woman with sepsis was hospitalised with improved condition despite 7 h of ED care. Interviews revealed the waiting time to see doctors was probably the top priority issue for patients.ConclusionsFactors related to LOS in a rural hospital in Thailand are similar and in contrast to those of a previous study in a medical school setting. Reasons for the discrepancy of findings and implications for improving ED services were discussed. Our data support the notion of controversy in using LOS as a key indicator of ED performance in this rural hospital setting. Thus, it is imperative to not rely on any single throughput or process indicators to monitor ED performance, but to take into account a set of indicators including patient outcomes.
Dietary enrichment of edible insects with omega 3 fatty acids

Published: February 2019

AbstractEdible insects are advocated as sustainable and healthy food and feed. However, commercially produced insects are often low in n‐3 fatty acids and have suboptimal n‐6/n‐3 ratios. A certain amount and proportion of these FAs is required to optimize human health. Flaxseed oil consists primarily (57%) out of alpha‐linolenic acid. An experiment was conducted to quantify the effect of flaxseed oil provision on fatty acid composition and to determine the quantity needed to attain a beneficial n‐6/n‐3 ratio. Three species were used in the experiment: house crickets (Acheta domesticus [L.]), lesser mealworms (Alphitobius diaperinus [Pfanzer]) and black soldier flies (Hermetia illucens [L.]). These were provided with either a control diet or a diet enriched with 1%, 2%, or 4% flaxseed oil during their larval/nymphal stage. Fatty acid profiles of diets and insects were determined via GC‐MS. The three species had distinct fatty acid profiles on all four diets, but responded similarly to flaxseed oil addition. For each percent added to the diet, the alpha‐linolenic acid content of the insects increased by 2.3%–2.7%. Four percent addition increased the n‐3 fatty acid content 10–20 fold in the three species and thereby strongly decreased n‐6/n‐3 ratios from 18–36 to 0.8–2.4. A ratio below 5 is considered optimal for human health and was achieved by 2% flaxseed oil inclusion for house crickets and lesser mealworms, and at 1% inclusion for black soldier flies. Adding a source of n‐3 fatty acids to insect diets can thus improve the nutritional quality of insects.

BackgroundTo evaluate whether pre‐emptive skin analgesia using a lidocaine patch 5% would improve the effects of systemic morphine analgesia for controlling acute post‐thoracotomy pain.MethodsThis was a double‐blind, placebo controlled, prospective study. Patients were randomly assigned to receive lidocaine 5% patch (lidocaine group) or a placebo (placebo group) three days before thoracotomy. Postoperative analgesia was induced in all cases with intravenous morphine analgesia. The intergroup differences were assessed in order to evaluate whether the lidocaine patch 5% would have effects on pain intensity when at rest and after coughing (primary end‐point) on morphine consumption, on the recovery of respiratory function, and on peripheral painful pathways measured with N2 and P2 laser‐evoked potential (secondary end‐points).ResultsA total of 90 patients were randomized, of whom 45 were allocated to the lidocaine group and 45 to the placebo group. Lidocaine compared with the placebo group showed a significant reduction in pain intensity both at rest (P = 0.013) and after coughing (P = 0.015), and in total morphine consumption (P = 0.001); and also showed a better recovery of flow expiratory volume in one second (P = 0.025) and of forced vital capacity (P = 0.037). The placebo group compared with the lidocaine group presented a reduction in amplitude of N2 (P = 0.001) and P2 (P = 0.03), and an increase in the latency of N2 (P = 0.023) and P2 (P = 0.025) laser‐evoked potential.ConclusionsThe preventive skin analgesia with lidocaine patch 5% seems to be a valid adjunct to intravenous morphine analgesia for controlling post‐thoracotomy pain. However, our initial results should be corroborated/confirmed by larger studies.
Gender Differences in Use of Alcohol Treatment Services and Reasons for Nonuse in a National Sample

Published: February 2019

BackgroundThe majority of adults with alcohol use disorders do not obtain help, and women are less likely to utilize alcohol services than men. We sought to quantify gender differences in alcohol services utilization, overall and by type, using national longitudinal data and to explore potential gender differences in perceived need for help and reasons for not seeking help.MethodsWe analyzed data from the National Epidemiologic Survey on Alcohol and Related Conditions from White, African American, and Hispanic adults (n = 2,592) who met DSM‐IV criteria for alcohol abuse or dependence at Wave 1 (2000 to 2001). We tested gender differences in Wave 2 (2004 to 2005) services utilization, perceived need for help, and treatment barriers using Rao‐Scott chi‐square tests and assessed predictors of outcomes in multivariable logistic regression, adjusting for problem severity, co‐occurring disorders, and demographics.ResultsWomen had much lower odds than men of utilizing any alcohol service (adjusted odds ratio [aOR] 0.53; 95% confidence interval [95% CI]: 0.33, 0.86), specialty services (aOR 0.41; 95% CI 0.19, 0.87), and 12‐step groups (aOR 0.39; 95% CI 0.21, 0.71). Perceived need for help among those who had not used any services was very low (5%), with no gender difference. Further, men and women reported equivalent numbers of treatment barriers and the same rank order for the most frequently endorsed barriers. However, women were twice as likely as men to think a problem would get better by itself—the most frequent reason for not seeking help (47% vs. 24%, p < 0.001), and men were more likely than women to report unsuccessful past help‐seeking and not thinking anyone could help (19% vs. 3%, p < 0.001 and 17% vs. 5%, p = 0.001, respectively).ConclusionsConsistent with previous studies, women were less likely to utilize alcohol services than men. Future interventions should address low problem recognition, and tailoring to gender‐specific barriers may help close the disparity in services utilization.
