Authors: Savolainen Jussi Matias , Saari Arto , Männistö Anssi , Kähkonen Kalle 
Published: August 2018

PurposeDesign management plays a significant role in value creation in a construction project. Within the last few decades, new design tools such as building information model have been introduced, which supposedly enhance design productivity and quality. However, no such revolution of design quality has emerged. Therefore, more research on how design management affects the quality of construction project is needed. The purpose of this paper is to better understand the connection between design management procedures and quality.Design/methodology/approachThis is a case study with a mixed-method approach. The data collection strategies used are quantitative user satisfaction survey and qualitative analysis over the documentation of the case project.FindingsA deductive analysis was conducted to four suggested indicators of beneficial collaboration. An explanation was found for how the quality of the project outcome can be forecasted from the management style and procedures.Research limitations/implicationsThe research was conducted as single case study, and therefore, greater data would enable further development of the indicators.Practical implicationsThe indicators have wide range of applicability: the clients can forecast the quality performance by evaluating the management procedures already during the project instead of waiting until the end of project. The indicator system also provides societal impact as it guides the clients to use the kind of managerial practices that improve the ability to create value in projects that are difficult to evaluate in money terms.Originality/valueThe research provides a novel way to gain a holistic view with analytical indicator tools. The research contributes to lean design management literature by providing insight to the underlying mechanism of beneficial collaboration.
Perceived supervisor support and turnover intention: moderating effect of authentic leadership
Authors: Arici Hasan Evrim 
Published: August 2018

PurposeThe purpose of this paper is to investigate the moderating role of authentic leadership (AL) on the relationship between seasonal employee’s perception of supervisor support and turnover intention (TI) in the hospitality industry.Design/methodology/approachThe data on perceived supervisor support (PSS), AL and TI were gathered from 305 seasonal employees of five-star hotels in Antalya, Turkey with a time lag of one month. Hierarchical linear regression and hierarchical linear modeling were performed to test the multi-level data.FindingsThe findings revealed direct significant effects of both supervisor support and AL on TI. In addition, AL moderated the negative influence of PSS on TI.Research limitations/implicationsThis multi-level research highlights the significance of AL for comprehending the link between seasonal hotel employees’ PSS and their TI. Directions for future research include a cross-cultural study examining the validity of the conceptual framework. Confirmatory factor analysis was performed to check the common method variance.Practical implicationsAL through strengthening PSS works as a catalyst for keeping seasonal employees in the organization for the next season. Thus, practitioners should develop supervisors’ AL skills and they should encourage supervisors to be more efficient in improving themselves as a main source of support.Originality/valueThe research investigates the little-researched area of AL at the group level in relation to PSS and TI.

Authors: Singh Rohit Kumar , Kansara Surendra , Vishwakarma Niraj Kumar 
Published: August 2018

Purpose
The aim of this paper is to identify the criteria that are used for vendor or supplier rating, prioritize these criteria based on the industry inputs and develop a vendor rating model. The data were collected from an Indian start-up working in product development using three-dimensional printing (3DP).

Design/methodology/approach
Factors of importance for vendor rating were identified through industry visits, and interacting with the industry experts from the start-up under consideration, substantiated by extensive review of relevant literature. A questionnaire-based survey was carried out to further narrow down the factors important to the industry, prioritizing them with a pairwise comparison analysis as envisaged in the analytical hierarchy process (AHP) technique along with the calculation of consistency ratios. Technique for order preference by similarity to ideal solution (TOPSIS) methodology was further used for data aggregation.

Findings
This research brought forward the criteria that are useful for rating vendors or suppliers with reference to 3DP sector.

Originality/value
This paper integrates AHP and TOPSIS to solve a multi-criteria vendor rating problem. The attempt was made to make vendor rating process universal so that it can encompass all the vendors of the firm.
The rapid diffusion of license plate readers in US law enforcement agencies
Authors: Lum Cynthia , Koper Christopher S. , Willis James , Happeny Stephen , Vovak Heather , Nichols Jordan 
Published: August 2018

Purpose
The purpose of this paper is to document the diffusion of license plate readers (LPRs) in the USA, examining the variety, evolution and tracking of their uses through a national survey.

Design/methodology/approach
This study employs a national, stratified, representative survey of US law enforcement agencies with 100 or more officers.

Findings
LPR technology is currently used by at least two-thirds of larger police agencies, which represents a more than threefold increase in LPR acquisition in the last 10 years. The number of LPRs per agency, while small (about eight on average), has also more than doubled. Federal and state funding, advocacy by law enforcement leaders, and the intuitive appeal of LPRs have likely contributed to this rapid adoption. While LPRs are still primarily used to detect and recover stolen automobiles in patrol, their use has expanded into other types of investigative and security functions. Despite the increased use and numbers of LPRs in policing, their use is highly discretionary and infrequently tracked.

Practical implications
LPRs continue to be widely used in law enforcement, despite a lack of strong research evidence for their crime prevention benefits. Further studies are needed on the most effective ways for agencies to utilize small numbers of LPRs and the potential return on investment for acquiring larger numbers of the devices.

Originality/value
This study tracks the history of LPR diffusion and use and goes beyond prior law enforcement surveys by examining specific uses of LPRs and the extent to which agencies track their uses and outcomes.
Predicting credit risk on the basis of financial and non-financial variables and data mining
Authors: Khemakhem Sihem , Boujelbene Younes 
Published: August 2018

PurposeData mining for predicting credit risk is a beneficial tool for financial institutions to evaluate the financial health of companies. However, the ubiquity of selecting parameters and the presence of unbalanced data sets is a very typical problem of this technique. This study aims to provide a new method for evaluating credit risk, taking into account not only financial and non-financial variables, but also the class imbalance.Design/methodology/approachThe most significant financial and non-financial variables were determined to build a credit scoring model and identify the creditworthiness of companies. Moreover, the Synthetic Minority Oversampling Technique was used to solve the problem of class imbalance and improve the performance of the classifier. The artificial neural networks and decision trees were designed to predict default risk.FindingsResults showed that profitability ratios, repayment capacity, solvency, duration of a credit report, guarantees, size of the company, loan number, ownership structure and the corporate banking relationship duration turned out to be the key factors in predicting default. Also, both algorithms were found to be highly sensitive to class imbalance. However, with balanced data, the decision trees displayed higher predictive accuracy for the assessment of credit risk than artificial neural networks.Originality/valueClassification results depend on the appropriateness of data characteristics and the appropriate analysis algorithm for data sets. The selection of financial and non-financial variables, as well as the resolution of class imbalance allows companies to assess their credit risk successfully.
Learning-structure fit part I
Authors: Sitar Aleša Saša , Škerlavaj Miha 
Published: August 2018

PurposeThe purpose of this study, which consists of two parts, is to bring together literature on organizational design and learning of individuals in organizational settings. The literature suggests that learning takes place in organic and less-structured organizational designs, whereas empirical research provides conflicting evidence. This first part theorizes about the influence of mechanistic vs organic designs on three different aspects of employees’ learning behavior: knowledge sourcing, learning styles and learning loops.Design/methodology/approachThis paper is built on previous research on the impact of structure on learning and theorizes about the relationship between mechanistic/organic design and specific learning behavior at work.FindingsFour propositions are developed in this paper, regarding how a different structure leads to a different learning behavior. Mechanistic structure is associated with internal learning, independent learning and single-loop learning, whereas organic design leads to external learning, collaborative learning and double-loop learning.Research limitations/implicationsBecause the paper is conceptual in nature, the propositions are in need of empirical validation. Some directions for empirical testing are proposed.Practical/implicationsFor an organization design practice, managers should be aware of the distinct impact different structures have on individual learning at work. Furthermore, the appropriate organizational structure for learning must be considered in the broader context of contingencies.Originality/valueThis paper contributes to the organizational design literature and to the organizational learning theory by conceptualizing the relationship between structure and learning of individuals at work.
Venom of prey‐specialized spiders is more toxic to their preferred prey: A result of prey‐specific toxins

Published: August 2018

Abstract

In specialized predators, a variety of adaptations have evolved to such a level of specificity that they allow very effective exploitation of focal prey. Venom is an essential adaptive trait of predatory venomous species, such as spiders, yet our knowledge of spider venom is incomplete.

In agreement with the prey preference hypothesis, we expected that the venom of spider specialists should be more toxic to focal than to alternative prey, because it is composed of prey‐specific toxins.

Here we used spiders with three types of trophic specializations: specialists that were ant‐eating, termite‐eating and spider‐eating. We compared the efficacy of prey capture of preferred and alternative prey (measured as paralysis latency) with that of related generalists and profiled the venom of the studied species using proteomic methods. We used 22 spider species: six myrmecophagous, two termitophagous, three araneophagous and 11 euryphagous generalist species belonging to different families.

We found that ten of the eleven specialist species induced significantly shorter paralysis latency in preferred prey than in alternative prey. Generalists exhibited either similar efficiency on both prey types or slightly higher efficiency on preferred prey.

Multivariate analysis of proteomic profiles (peptides and proteins) revealed significant differences between trophic specializations, particularly in peptides. Specialists appear to have venom composed of unique specific compounds as revealed by the multivariate ordination and indicator analysis. These components are likely prey‐specific toxins.

Summary
Pyricularia oryzae is a plant pathogen causing rice blast, a serious disease spreading in cultivated rice globally. Transcription factors play important regulatory roles in fungal development and pathogenicity. Here, we characterized the biological functions of Crf1, a basic helix–loop–helix (bHLH) transcription factor, in the development and pathogenicity of P. oryzae with functional genetics, molecular and biochemical approaches. We found that CRF1 is necessary for virulence and plays an indispensable role in the regulation of carbohydrate and lipid metabolism in P. oryzae. Deletion of CRF1 led to defects in utilization of lipids, ethanol, glycerol and L‐arabinose, and down‐regulation of many important genes in lipolysis, β‐oxidation, gluconeogenesis, as well as glycerol and arabinose metabolism. CRF1 is also essential for peroxisome and vacuole function, and conidial cell death during appressorium formation. The appressorium turgor, penetration ability and virulence in Δcrf1 were restored by supplementation of exogenous glucose. The virulence of Crf1 mutant was also recovered by adding exogenous D‐xylose, but not by addition of ethanol, pyruvate, leucine or L‐arabinose. These data showed that Crf1 plays an important role in the complex regulatory network of carbohydrate and lipid metabolism that governs fungal development and pathogenicity.

Published: August 2018

The aim of the present study was to develop new molecularly imprinted polymers (MIPs) to coat stainless steel plates for the removal of aflatoxin M1 (AFM1), which is a serious concern in the safety of milk and dairy products. Scanning electron microscopy, energy dispersive spectroscopy, and Fourier‐transform infrared spectroscopy tests confirmed that MIPs successfully coated the stainless steel plates. The MIPs were applied to extract AFM1 from milk spiked with 0.5 to 50 ng/mL AFM1. The MIPs removed 87.3–96.2% of the AFM1 without any notable effects on the milk composition. The results also showed that the imprinting factors of DMC, AFM1, AFB1, and AFG1 were 5.93, 4.61, 3.41, and 2.72, respectively.

Published: August 2018

AbstractObjectivesTo compare patient satisfaction levels, staff perspectives and the time required using Structured Interdisciplinary Bedside Rounds (SIBR; Emory University, Atlanta, GA, USA) versus traditional medical ward rounds (TR) in the ED.MethodsWe conducted an observational cross‐sectional study. Ward rounds were categorised into a modified SIBR and TR at a tertiary ED in Australia according to predefined criteria. We compared the duration of ward rounds, invited patients and staff to complete anonymous questionnaires to compare patient satisfaction and staff perspectives.ResultsDuring the study period, SIBR group took significantly longer time than TR per patient (122 vs 88 s, P < 0.001). Patient questionnaires were completed for 320 encounters (101 SIBR, 219 TR). Patient satisfaction scores across all measured domains were significantly higher in SIBR than in the TR group. Patients often pointed out a lack of communication with medical staff during TR. Based on 131 completed staff questionnaires, nurses reported SIBR to be more useful than TR (nurses 78% vs doctors 44%, P = 0.001). The SIBR group had increased instances of staff introductions to patients (91% vs 66%, P < 0.001) and patients’ involvement in discussion of management plans (98% vs 53%, P < 0.01). SIBR only weakly correlated with the overall positive experience in the ED (r = 0.19, P = 0.001). Organisational implementation issues raised through qualitative methods are reported in the paper.ConclusionsOur study highlights the benefits that could be gained through SIBR technique over the TR method. Better workforce and resource planning is needed to support the sustainable implementation of SIBR in ED.

BackgroundPrevious studies have shown amrubicin (AMR) to be an effective second‐line treatment option for small‐cell lung cancer (SCLC). However, the efficacy of AMR in elderly patients with relapsed SCLC has not been sufficiently evaluated.MethodsThe medical records of elderly patients with relapsed SCLC who received AMR as second‐line chemotherapy were retrospectively reviewed, and their treatment outcomes were evaluated.ResultsThirty‐one patients with a median age of 72 years (22 patients with sensitive relapse and 9 with refractory relapse) were analyzed. The median number of treatment cycles was four (range: 1–10), and the response rate was 29%. The median progression‐free survival (PFS) and overall survival (OS) were 5.4 and 11.6 months, respectively. The OS of 22 patients who received third‐line chemotherapy was 15.5 months. The PFS (6.2 vs. 3.2 months; P = 0.002) and OS (14.8 vs. 5.7 months; P = 0.004) were significantly longer in patients with sensitive relapse than those with refractory relapse. The frequency of grade 3 or higher neutropenia was high (n = 18, 58%), while febrile neutropenia was only observed in five patients (16%). Non‐hematological toxic effects were relatively mild, and pneumonitis and treatment‐related deaths were not observed.ConclusionAMR may be a feasible and effective regimen for elderly patients with relapsed SCLC.

Published: August 2018

BackgroundApatinib, a small‐molecule inhibitor of vascular endothelial growth factor receptor 2 (VEGFR‐2), has proven to be effective and safe for treating patients with advanced gastric cancer after second‐line chemotherapy failure. As VEGFR‐2 targeted therapy has made encouraging progress for the treatment of a broad range of malignancies, we explored the efficacy and safety of apatinib for the treatment of advanced non‐small cell lung cancer after the failure of chemotherapy or other targeted therapy.MethodsWe retrospectively analyzed the data of 34 patients (11 with squamous carcinoma and 23 with adenocarcinoma) who were treated with apatinib alone in a daily oral dose of 250 mg in the second‐line or third‐line setting from January 2016 to July 2017. The primary endpoint was progression‐free survival (PFS).Results
EGFR mutation or amplification was detected in 15 patients. The median PFS of the whole group was four months (95% confidence interval 0.3–7.7). A partial response was observed in 2 patients (5.88%) and stable disease in 19 (55.88%). The disease control rate was 61.76%. Common side effects of apatinib were hypertension (n = 12), hand‐foot syndrome (n = 8), and proteinuria (n = 5), which accounted for 35.30%, 23.53%, and 14.71%, respectively, and no grade 3/4 adverse reactions occurred. Apatinib toxicity was controllable and tolerable.ConclusionsApatinib appears to be effective and safe for advanced non‐small cell lung cancer after the failure of chemotherapy or other targeted therapy.

Published: August 2018

BackgroundAlthough phase III trials have shown improved overall and progression‐free survival (PFS) using nivolumab compared to docetaxel in patients with non‐small‐cell lung cancer, the progressive disease ratio of nivolumab is higher than docetaxel. Furthermore, nonconventional response patterns of nivolumab make it difficult to determine the time point for nivolumab discontinuation. Therefore, a method to detect non‐responders to nivolumab at an early time point is crucial. This retrospective study was conducted to identify immunological and nutritional markers, including neutrophil‐to‐lymphocyte ratios (NLR), which would predict the efficacy of nivolumab treatment. Because the expression of these markers fluctuates dramatically during treatment, repeat evaluation was performed.MethodsWe retrospectively investigated 30 patients with non‐small‐cell lung cancer who were treated with nivolumab. The stratified data of each marker obtained during four weeks after nivolumab treatment were evaluated by Cox proportional hazards regression to verify the differences in PFS.ResultsOne and four patients experienced progressive disease within two and four weeks, respectively. Therefore, 29 and 26 patients were analyzed two and four weeks after nivolumab administration, respectively. The results showed that the NLR after four weeks could predict PFS. The median PFS in 21 patients with NLR < 5 after four weeks of nivolumab administration was 95 days (95% confidence interval [CI] 50–NA), while the mPFS in five patients with NLR ≥ 5 was 10 days (95% CI 6–NA). NLR ≥ 5 showed a hazard ratio of 5.995 (95% CI 1.225–29.35).ConclusionClarifying NLR four weeks after nivolumab administration may be useful to predict outcomes in nivolumab‐treated patients.
