Load planning processes to enhance cargo compartment utilization
Authors: Carlson Nathan J. , Reiman Adam. D. , Overstreet Robert E. , Douglas Matthew A. 
Published: April 2018

Purpose
The United States Air Force often provides effective airlift for cargo distribution, but is at times inefficient. This paper aims to address the under-utilization of military airlift cargo compartments that plagues the airlift system.

Design/methodology/approach
The authors examine seven techniques designed to increase cargo compartment utilization and increase airlift utilization rates. The techniques were applied through load planning software to 30 real-world movements consisting of 159 sorties. They then ran each post-technique movement through a modeled flight environment to obtain cycle movement data. The metrics gained from both the load planning software and the modeled environment were regressed to provide statistical understanding regarding how well each technique influenced cost savings.

Findings
The results showed a 24 per cent elimination of aircraft required and a savings of $14.5m. Extrapolation of the authors’ findings to four years of airlift mission data revealed an estimated annual savings of $1.6bn.

Originality/value
This research effort provides multiple options to improve the efficiency and effectiveness of military airlift.
Towards circular economy – a wastewater treatment perspective, the Presa Guadalupe case
Authors: Casiano Flores Cesar , Bressers Hans , Gutierrez Carina , de Boer Cheryl 
Published: April 2018

Purpose
In Mexico, only 19.3 per cent of industrial water is treated (Green-Peace, 2014, pp. 3-4), whereas municipal treatment levels are approximately 50 per cent (CONAGUA, 2014a). This paper aims to focus on how the wastewater treatment plant policy, from a circular economy perspective, is affected by the governance context at the Presa Guadalupe sub-basin. Circular economy can contribute to water innovations that help in improving water quality. However, such benefits are not easily achieved. This case provides an example of the complexity and challenges that the implementation of a circular economy model can face.

Design/methodology/approach
Data are collected via semi-structured in-depth interviews with the stakeholders that are members of the Presa Guadalupe Commission. The contextual interaction theory (CIT) is the theoretical basis for this analysis (Boer de and Bressers, 2011; Bressers, 2009).

Findings
The findings show that the wastewater treatment plant policy plays an important role in a circular economy model. Some incentives towards a circular economy model are already in place; however, the hurdles of a top-down implementation perspective, low availability of resources, prioritisation of short-term results, lack of enforcement of the “polluter pays” principle and a linear model of water systems need to be overcome. If Mexico wants to move towards a circular economy model and if the government wants to enforce sustainable development principles, wastewater treatment is a challenge that must be addressed.

Originality/value
There are few studies in the circular economy literature that have analysed its implementation under a governance arrangement perspective.
The relation between corporate governance mechanisms, executive compensation and audit fees
Authors: Salehi Mahdi , Tarighi Hossein , Safdari Samaneh 
Published: April 2018

PurposeThis paper aims to investigate the effects of some corporate governance mechanisms and executive compensation on audit fees in an emerging market.Design/methodology/approachThe study population consists of 540 observations and 90 listed companies on the Tehran Stock Exchange during the years 2009-2014. The statistical model used in this study is a multivariate regression model; besides, the statistical technique used to test the hypotheses proposed in this research is panel data.FindingsThe changes in the value of a CEO’s own firm stock option portfolio, in thousands of rials (Iran’s currency), for a 0.01 change in stock return volatility and stock price are defined as Vega and Delta, respectively. The results demonstrated that there is a positive association between audit fees and delta, but not Vega; this means that a fee premium is linked to CEO Delta incentives. The findings show that Iranian companies pay more audit fees when they give managers more rewards. In addition, the results show that there is not a significant relationship between fees resulting from audit risk and Delta and Vega incentives of the board. Inconsistent with agency theory, the authors found that the independence of board members did not have any effect on audit fees. As a final point, the outcomes of the paper demonstrate that managers who invest in companies under their own management do not have any impact on the amount of audit fee. To put it another way, there is not any significant connection between the board ownership and audit fees.Practical implicationsThis is one of the most important studies that simultaneously surveys the impacts of corporate governance mechanisms and executive compensation in the Iranian audit market. The results of this study will reveal more than the role of corporate governance mechanisms for society and users of financial statements because as tools on the CEO actions, they always have to pay attention to the implementation of corporate principles in the economic entity’ operation.Originality/valueThe present study has examined the relationship between two cases of corporate governance mechanisms named the board independence and the board ownership with audit fees in a country where, to the authors’ knowledge as in most other developing markets, such a relationship has not been a subject of empirical research. Moreover, the use of a two-dimensional measure of executive compensation, namely, Delta and Vega incentives, primarily considering research undertaken in an emerging market, as a valuable contribution may be observed.
Kaizen, a continuous improvement practice in organizations
Authors: Alvarado-Ramírez Karla María , Pumisacho-Álvaro Víctor Hipólito , Miguel-Davila José Ángel , Suárez Barraza Manuel F. 
Published: April 2018

Purpose
The purpose of this paper is to compare the practices of continuous improvement that are applied in medium and large manufacturing and service companies in two Latin American countries. At the same time, benefits and barriers experienced by these companies with regard to sustainability of continuous improvement are explored.

Design/methodology/approach
In order to generate a comparative study between two Latin American countries, interviews were conducted with managers linked to continuous improvement in medium and large companies in the State of Puebla and the Metropolitan District of Quito, which are important areas in Mexico and Ecuador, respectively. Data were collected by means of document analysis, semi-structured interviews, and direct observation.

Findings
Companies in both countries identify the use of various techniques and/or tools for continuous improvement. The results of the empirical evidence show how the impact of the application of the techniques has been beneficial in economic and human terms. Thus, the exploratory study has permitted the identification of the drivers and inhibitors in the maintenance of continuous improvement.

Research limitations/implications
The research is based on only two areas of the Latin American countries: Mexico and Ecuador. Their results can therefore not be generalized. The approach is applied in a specific environment, namely, the State of Puebla and the Metropolitan District of Quito. This study incorporates the perception of managers, directors, and/or supervisors involved in continuous improvement processes.

Practical implications
This paper seeks to provide analytical input. The study is of great interest to researchers, managers, consultants, and professionals linked to projects of continuous improvement who wish to incorporate continuous improvement practices which are sustainable over time. A new managerial behavior is the basis of continuous improvement, where the training and development of the human resource increases the commitment to achieve organizational changes.

Originality/value
This research makes an empirical contribution to the literature through the understanding of practices of continuous improvement in a Latin American context, highlighting the factors that improve or impede the process of continuous improvement. Particularly in Mexico and Ecuador, the empirical evidence on this subject is still scarce despite the existence of theoretical academic literature.
The quality movement from six perspectives
Authors: Miller William J. , Duesing Robert J. , Lowery Christopher M. , Sumner Andrew T. 
Published: April 2018

Purpose
The purpose of this paper is to examine the quality movement in the framework of an organizing taxonomy model from six perspectives: global trend, national mandate, industry trend, organizational strategy, operational strategy, and personal philosophy.

Design/methodology/approach
The authors use the organizing taxonomy model to analyze the quality movement from each of the six perspectives in terms utilizing a diverse range of key questions, characteristics, and issues which must be addressed.

Findings
The analysis shows that viewing the quality movement from these various perspectives can help practitioners in developing an understanding of the quality movement not only from a historical standpoint, but also in terms of current requirements and future demands. This can also benefit quality management researchers in terms of organizing the focus of their research on the various perspectives. The organizing taxonomy model can also be used to assess other phenomena such as lean, supply chain management, knowledge management, and business analytics which are similarly impacting organizations across all industries and throughout the world.

Originality/value
The paper presents a fresh look at the quality movement from a range of perspectives and provides insight into an organized method of assessing major movements that continue to impact businesses globally.
Carpooling: travelers’ perceptions from a big data analysis
Authors: Ciasullo Maria Vincenza , Troisi Orlando , Loia Francesca , Maione Gennaro 
Published: April 2018

Purpose
The purpose of this paper is to provide a better understanding of the reasons why people use or do not use carpooling. A further aim is to collect and analyze empirical evidence concerning the advantages and disadvantages of carpooling.

Design/methodology/approach
A large-scale text analytics study has been conducted: the collection of the peoples’ opinions have been realized on Twitter by means of a dedicated web crawler, named “Twitter4J.” After their mining, the collected data have been treated through a sentiment analysis realized by means of “SentiWordNet.”

Findings
The big data analysis identified the 12 most frequently used concepts about carpooling by Twitter’s users: seven advantages (economic efficiency, environmental efficiency, comfort, traffic, socialization, reliability, curiosity) and five disadvantages (lack of effectiveness, lack of flexibility, lack of privacy, danger, lack of trust).

Research limitations/implications
Although the sample is particularly large (10 percent of the data flow published on Twitter from all over the world in about one year), the automated collection of people’s comments has prevented a more in-depth analysis of users’ thoughts and opinions.

Practical implications
The research findings may direct entrepreneurs, managers and policy makers to understand the variables to be leveraged and the actions to be taken to take advantage of the potential benefits that carpooling offers.

Originality/value
The work has utilized skills from three different areas, i.e., business management, computing science and statistics, which have been synergistically integrated for customizing, implementing and using two IT tools capable of automatically identifying, selecting, collecting, categorizing and analyzing people’s tweets about carpooling.
Level of empathy among dietitians: A pilot study
Authors: Yang Wai Y. , Fu Yen 
Published: April 2018

AimThe health‐care providers’ empathy has been linked to better patient outcomes. The increased demand for dietetics services has called for dietitians to examine their clinical practices and encounters with patients. To date, there are limited studies published on empathy among dietitians. Hence, this study aimed to determine the clinical dietitians’ empathy level in Malaysia.MethodsUsing a purposive sampling method, this study was conducted on dietitians practising in the Malaysian hospitals (government and private). The Toronto Empathy Questionnaire (TEQ), a validated 16‐item questionnaire was self‐administered, either by online survey method or face‐to‐face method. Additional information on gender, ethnicity, years of experience and percentage of working time spent on clinical, administrative and other areas were collected.ResultsA total of 69 dietitians participated in the study (private (n = 36) and government (n = 33)). The dietitians’ mean total TEQ scores were 49.72 ± 5.62 (score ranged between 35 and 63). Significant difference of mean total TEQ scores was found between dietitians from private (51.06 ± 5.26) and government hospitals (48.27 ± 5.72). There was no significant difference in the level of empathy by gender, ethnicity, years of experience and percentage of time spent on clinical consultations, administration or others while at work.ConclusionsResults from this study showed that there were differences in empathy level of Malaysian dietitians by work setting. This preliminary finding serves as a baseline for future studies and could facilitate the development of dietetics education in Malaysia.
Utility of pooled sequencing for association mapping in nonmodel organisms
Authors: Micheletti Steven J. , Narum Shawn R. 
Published: April 2018

AbstractHigh‐density genome‐wide sequencing increases the likelihood of discovering genes of major effect and genomic structural variation in organisms. While there is an increasing availability of reference genomes across broad taxa, the greatest limitation to whole‐genome sequencing of multiple individuals continues to be the costs associated with sequencing. To alleviate excessive costs, pooling multiple individuals with similar phenotypes and sequencing the homogenized DNA (Pool‐Seq) can achieve high genome coverage, but at the loss of individual genotypes. Although Pool‐Seq has been an effective method for association mapping in model organisms, it has not been frequently utilized in natural populations. To extend bioinformatic tools for rapid implementation of Pool‐Seq data in nonmodel organisms, we developed a pipeline called PoolParty and illustrate its effectiveness in genetic association mapping. Alignment expectations based on five pooled Chinook salmon (Oncorhynchus tshawytscha) libraries showed that approximately 48% genome coverage per library could be achieved with reasonable sequencing effort. We additionally examined male and female O. tshawytscha libraries to illustrate how Pool‐Seq techniques can successfully map known genes associated with functional differences among sexes such as growth hormone 2. Finally, we compared pools of individuals of different spawning ages for each sex to discover novel genes involved with age at maturity in O. tshawytscha such as opsin4 and transmembrane protein19. While not appropriate for every system, Pool‐Seq data processed by the PoolParty pipeline is a practical method for identifying genes of major effect in nonmodel organisms when high genome coverage is necessary and cost is a limiting factor.
Immature stages of the turquoise‐banded shoemaker Archaeoprepona amphimachus pseudomeander (Fruhstorfer, 1906) and a comparative review of the Preponini (Lepidoptera: Nymphalidae)
Authors: Dias Fernando Maia Silva , Casagrande Mirna Martins , Mielke Olaf Hermann Hendrik 
Published: April 2018

AbstractWe describe the external morphology and natural history of the immature stages of the turquoise‐banded shoemaker Archaeoprepona amphimachus pseudomeander (Fruhstorfer, 1906) (Charaxinae: Preponini), found in a forest fragment in Curitiba, Paraná, Brazil. Immature stages of this species use two species of Cinnamomum (Lauraceae) as host plants. We also provide morphological descriptions and illustrations and discuss morphological characteristics of taxonomic significance of immature stages of other species of Preponini known to date. These data support the synonymisation of Noreppa Rydon, 1971 with Archaeoprepona Fruhstorfer, 1844 and the close relationship between species formerly included in Agrias Doubleday, 1844 and the other species of Prepona Boisduval, [1836]. Our results agree with recent morphological and molecular findings, supporting the assertion that immature stages are an important source of information for systematics.
Detection of genetic variants between different Polish Landrace and Puławska pigs by means of RNA‐seq analysis
Authors: Piórkowska K. , Żukowski K. , Ropka‐Molik K. , Tyra M. 
Published: April 2018

SummaryVariant calling analysis based on RNA sequencing data provides information about gene variants. RNA‐seq is cheaper and faster than is DNA sequencing. However, it requires individual hard filters during data processing due to post‐transcriptional modifications such as splicing and RNA editing. In the present study, RNA‐seq transcriptome data on two Polish pig breeds (Puławska, PUL, n = 8, and Polish Landrace, PL, n = 8) were included. The pig breeds are significantly different with regard to meat qualities such as texture, water exudation, growth traits and fat content in carcasses. A total of 2451 significant mutations were identified by a chi square tests, and functional analysis was carried out using Panther, KEGG and Kobas. Interesting missense gene variants and mutations located in regulatory regions were found in a few genes related to fatty acid metabolism and lipid storage such as ACSL5, ALDH3A2, FADS1, SCD, PLA2G12A and ATGL. A validation of mutational influences on pig traits was performed for ALDH3A2, ATGL, PLA2G12A and MYOM1 variants using association analysis including 215 pigs of the PL and PUL breeds. The ALDH3A2ENSSSCT00000019636.2:c.470T>C polymorphism was found to affect the weight of the ham and loin eye area. In turn, an ENSSSCT00000004091.2:c.2836G>A MYOM1 mutation, which could be implicated in myofibrillar network organisation, had an effect on meatiness and loin texture parameters. The study aimed to estimate the usefulness of RNA‐seq results for a purpose other than differentially expressed gene analysis. The analysis performed indicated interesting gene variants that could be used in the future as markers during selection.
Employing the CEO of Me, Inc.: US corporate hiring in a neoliberal age
Authors: GERSHON ILANA 
Published: April 2018

ABSTRACTSocial practices and contingencies always exceed the neoliberal models by which people currently try to contain the inherent unpredictability of accomplishing social tasks with others, such as getting a job. Contradictions in neoliberal logics emerge when people try to live according to neoliberal precepts, engaging with other social entities as though all are corporate persons and all alliances are, metaphorically speaking, business‐to‐business alliances. Moments in US corporate hiring challenge scholarly critiques of neoliberal logics that have made neoliberalism seem too reductive and too prescriptive. At such moments, Americans find that one neoliberal principle is incompatible in practice with a different neoliberal principle—as when, for example, being a flexible worker is antithetical to being a legible job candidate.
Operating room‐to‐incision interval and neonatal outcome in emergency caesarean section: a retrospective 5‐year cohort study
Authors: Palmer E. , Ciechanowicz S. , Reeve A. , Harris S. , Wong D. J. N. , Sultan P. 
Published: April 2018

SummaryWe conducted a 5‐year retrospective cohort study on women undergoing caesarean section to investigate factors influencing the operating room‐to‐incision interval. Time‐to‐event analysis was performed for category‐1 caesarean section using a Cox proportional hazards regression model. Covariates included: anaesthetic technique; body mass index; age; parity; time of delivery; and gestational age. Binary logistic regression was performed for 5‐min Apgar score ≥ 7. There were 677 women who underwent category‐1 caesarean section and who met the entry criteria. Unadjusted median (IQR [range]) operating room‐to‐incision intervals were: epidural top‐up 11 (7–17 [0–87]) min; general anaesthesia 6 (4–11 [0–69]) min; spinal 13 (10–20 [0–83]) min; and combined spinal‐epidural 24 (13–35 [0–75]) min. Cox regression showed general anaesthesia to be the most rapid method with a hazard ratio (95%CI) of 1.97 (1.60–2.44; p < 0.0001), followed by epidural top‐up (reference group), spinal anaesthesia 0.79 (0.65–0.96; p = 0.02) and combined spinal‐epidural 0.48 (0.35–0.67; p < 0.0001). Underweight and overweight body mass indexes were associated with longer operating room‐to‐incision intervals. General anaesthesia was associated with fewer 5‐min Apgar scores ≥ 7 with an odds ratio (95%CI) of 0.28 (0.11–0.68; p < 0.01). There was no difference in neonatal outcomes between the first and fifth quintiles for operating room‐to‐incision intervals. General anaesthesia is associated with the most rapid operating room‐to‐incision interval for category‐1 caesarean section, but is also associated with worse short term neonatal outcomes. Longer operating room‐to‐incision intervals were not associated with worse neonatal outcomes.

Published: April 2018

SummaryBone Scan Index (BSI) is a validated imaging biomarker to objectively assess tumour burden in bone in patients with prostate cancer, and can be used to monitor treatment response. It is not known if BSI is significantly altered when images are acquired at a time difference of 1 h. The aim of this study was to investigate if automatic calculation of BSI is affected when images are acquired 1 hour apart, after approximately 3 and 4 h. We prospectively studied patients with prostate cancer who were referred for bone scintigraphy according to clinical routine. The patients performed a whole‐body bone scan at approximately 3 h after injection of radiolabelled bisphosphonate and a second 1 h after the first. BSI values for each bone scintigraphy were obtained using EXINI boneBSI software. A total of 25 patients were included. Median BSI for the first acquisition was 0·05 (range 0–11·93) and for the second acquisition 0·21 (range 0–13·06). There was a statistically significant increase in BSI at the second image acquisition compared to the first (P<0·001). In seven of 25 patients (28%) and in seven of 13 patients with BSI > 0 (54%), a clinically significant increase (>0·3) was observed. The time between injection and scanning should be fixed when changes in BSI are important, for example when monitoring therapeutic efficacy.
